### What is the prime factorization 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 7
2 x 7 x 7 = 98
