In this worksheet, you must write numbers as the products of prime factors.

__Method__

All whole numbers, other than primes and the number 1, can be written as the product of their prime factors.

We find the prime factors of a number by successively dividing the number by prime numbers.

__Example__

Write **1800 **as the product of its prime factors.

Look at this division.

Here we pick out the red numbers to show that

1800 = 2^{3} × 3^{2} × 5^{2}
