Hence, Factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42
A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.
There are two different methods that can be used for the prime factorization.
To find the primefactors of 42 using the division method, follow these steps:
So, the prime factorization of 42 is, 42 = 2 x 3 x 7.
We can follow the same procedure using the factor tree of 42 as shown below:
So, the prime factorization of 42 is, 42 = 2 x 3 x 7.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 42 would be the two numbers which, when multiplied, give 42 as the result.
The following table represents the calculation of factors of 42 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 42 | 1 x 42 = 42 |
| 2 and 21 | 2 x 21 = 42 |
| 3 and 14 | 3 x 14 = 42 |
| 6 and 7 | 6 x 7 = 42 |
Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 42. They are called negative pair factors.
Hence, the negative pairs of 42 would be ( -1 , -42 ) , ( -2 , -21 ) , ( -3 , -14 ) and ( -6 , -7 ) .
In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.
Factors of -42 are -1, -2, -3, -6, -7, -14, -21, -42.
The sum of all factors of 42 is 96.
Prime factorization of 42 is 2 x 3 x 7.
Pair factors of 42 are (1,42), (2,21), (3,14), (6,7).
