Factors that 42 room the list of positive and an unfavorable whole numbers that deserve to be separated evenly right into 42. Negative factors the 42 room just components with a an adverse sign. The number 42 is far-reaching and is an also composite number which way that it has actually several factors, in this case, 42 has 8 factors. In this lesson, we will calculate the determinants of 42, its element factors, and its components in pairs. We will also shot a couple of solved instances to understand this subject better.

What are factors of 42?

Factors that a number are the numbers which divide the provided number precisely without leaving any type of remainder. Factors of 42 space 1, 2, 3, 6, 7, 14, 21 and 42.

How to calculate the components of 42?

We deserve to use different methods favor prime factorization and the division method to calculate the determinants of 42. In prime factorization, us express 42 as the product of its prime factors and in the division method, we look because that numbers that divide 42 specifically without a remainder.


Factors that 42 by element Factorization


Prime factorization means expressing a number in regards to the product the its prime factors. We have the right to do this using the division method or by making use of a variable tree.

Prime administrate by Division:

Step 1: The number 42 is separated by the the smallest prime number which divides 42 exactly, i.e. It pipeline a remainder 0.Step 2: The quotient is then divided by the the smallest or 2nd smallest prime number and the procedure continues it spins the quotient cannot be more divided.Step 3: Let us divide 42 through the prime number 2 i.e 42 ÷ 2 = 21.Step 4: Now we need to divide the quotient 21 by the next the very least prime number.Step 5: Since 21 is an odd number, that is not divisible by 2. Allow us shot dividing it by 3 i beg your pardon is 21 ÷ 3 = 7.Step 6: 7 is a prime number and we cannot division it further.Step 7: Therefore, the prime components of 42 are 2, 3, and also 7.

Prime factorization of 42 = 2 × 3 × 7

Prime administrate by aspect Tree

Since we space finding the prime components of 42, they will certainly be put as the roots of our factor tree. Next, we write a pair of factors (two numbers, when multiplied, give 42) together branches.

*

3 and 7 space prime numbers and at this point, the element tree ends. Let united state express 42 in regards to the product the its element factors.

42 = 2 × 3 × 7

Viola! We have done the prime factorization. Below is a basic activity to try on your own. Instead of 2 × 21, if we had actually used 6 × 7, execute you think us would obtain the very same factors? have the right to you draw the aspect tree v 6 and also 7 together the branches?

Prime administer by Upside-Down Division

This method is dubbed the upside-down department because the department symbol is flipped upside down. In this method, we division 42 through the the smallest prime number 2 (if the number is odd, we start with 3). 7 is a prime number. The is divisible just by 7. We protect against the division when we reach 1.

*

Therefore, 42 have the right to be expressed as a product of its prime factors together 2 × 3 × 7. Check out factors utilizing illustrations and interactive examples:

Think Tank:

8 × 21 ÷ 4 = 42, does this median 8 and 21 ÷ 4 are components of 42? Think!10.5 × 4 = 42, space 10.5 and 4 components of 42?Can a number better than 42 it is in its factor?

Factors of 42 in Pairs

Factor pairs space the 2 numbers which, as soon as multiplied, offer the number 42.

1 × 42 = 422 × 21 = 423 × 14 = 426 × 7 = 42

Therefore, the pair components of 42 room (1,42), (2,21), (3,14), and (6,7). Because the product the two an adverse numbers is positive, i.e. (-) × (-) = (+), the variable pairs that 42 also include (-1,-42), (-2,-21), (-3,-14), and (-6,-7). Yet let us emphasis on the positive determinants in this lesson.

We division 42 by natural numbers and see i m sorry numbers leaving a remainder 0. The numbers which divide 42 specifically without any remainder room the components of 42.

Division an approach to Find components of 42:

*

We view that when 42 is split by 1, 2, 3, 6, 7, 14, 21, and also 42, it leaves no remainder. Hence, lock are determinants of 42.

Important Notes:

The numbers which we multiply to obtain 42 space the factors of 42.Factors the 42 space 1, 2, 3, 6, 7, 14, 21, and also 42.1 is a global factor. That is a aspect of every numbers. The number chin is a element of the number together it divides itself exactly.Factor pairs room the bag of 2 numbers which, as soon as multiplied, provide the number. Factor pairs the 42 room (1, 42), (2, 21), (3,14), and (6,7).
