80 as a product of prime factors is 5 x 2 x 2 x 2 x 2.
<u>Step-by-step explanation:</u>
<em>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. </em>
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, <u>80 as a product of prime factors is 5 x 2 x 2 x 2 x 2.</u>
