Question

Write 80 as a product of prime factors.

Answer 1

• 80 as a product of prime factors is 5 x 2 x 2 x 2 x 2.

Explanation:

My method to solve this problem is to keep on dividing a number by 2's until the number is not divisible by 2. Next, I move on to 3. I divide 3 until that number is not divisible by 3 anymore. Then I divide it by 4,5,7, etc.

• 80 = 40 x 2
• => 40 x 2 = 20 x 2 x 2
• => 20 x 2 x 2 = 10 x 2 x 2 x 2
• => 10 x 2 x 2 x 2 = 5 x 2 x 2 x 2 x 2

Hence, 80 as a product of prime factors is 5 x 2 x 2 x 2 x 2.
