Question

Express the number 180 as a product of its prime factors

Answer 1

180 is even, so it's divisible by 2. 180/2 = 90. 
90 is even, so it's divisible by 2. 90/2 = 45 
45 is a multiple of 5; 45/5 = 9. 
9 is a multiple of 3; 9/3 = 3. 
3 is prime. Stop. List all prime numbers you used to get here, multiplied together, including the last one (from the step where you stopped) 

180 = 2 * 2 * 5 * 3 * 3. (Can also be expressed as 180 = 2^2 * 3^2 * 5.) 

Answer 2

Resolving 180 into Prime factorisation we get = 2 × 2 × 3 × 3 × 5
= 4 × 9 × 5 = 36 × 5
= 180
Hence, 180 is expressed as a product of its prime factors.
