What is the prime factorization of of 98?

The objective of prime factorization is, as the name implies, to find the prime numbers that divide that number exactly; that is, to find the factors of that number that are prime. This is done by dividing the given number (in this case, 98) by prime numbers until you cannot divide further. Given the number 98, then, let us start by dividing by 2. Division by 2 is typically a good starting point for even numbers, since 2 is prime. We are left with 49, and we now know that 2 is a prime factor. We can divide 49 by 7, leaving us with 7 and the knowledge that 2 and 7 are prime factors. We can't divide 7 any further, so it must be the last prime factor. In other words, 98 = 2 x 7 x 7. This is the prime factorization of 98.2 x 7 x 72 x 7 x 7 = 98


Will you get the same number of factors if you multiply a prime number and itself?

Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.


What is the decomposition for 42 98 56?

The decomposition of the numbers 42, 98, and 56 involves breaking them down into their prime factors. For 42: ( 42 = 2 \times 3 \times 7 ) For 98: ( 98 = 2 \times 7^2 ) For 56: ( 56 = 2^3 \times 7 ) Thus, the prime factorization of these numbers shows their respective components.
