How to find the divisors of 18-quora?
Any divisor of 240 will be of the form 2 a ∗ 3 b ∗ 5 c, where 0 ≤ a ≤ 4, 0 ≤ b ≤ 1, and 0 ≤ c ≤ 1. If we take all those possible combinations, we have ( 1 + 2 + 4 + 8 + 16) ∗ ( 1 + 3) ∗ ( 1 + 5). If we expand that product, we see that every summand is a divisor of 240, and there are no others, so that’s the sum we’re looking for.
How to calculate the quotient of factors of 18?
Since the Factors of 18 are all the numbers that you can evenly divide into 18, we simply divide 18 by all numbers up to 18 to see which ones result in an even quotient. When we did that, we found that these calculations resulted in an even quotient:
