Question

Find the GCF of 270 and 360

Answer 1

90

Explanation:

Divide the larger number by the smaller. Obtain the quotient and remainder.

If remainder is zero then smaller number is the GCF

If not then repeat the process with the remainder and smaller number until a remainder of 0 is reached.

`(360)/(270)` = 1 remainder 90, then

`(90)/(90)` = 1 remainder 0

Hence GCF is 90

90 = 2 × 3 × 3 × 5 =
`2^(1)` ×
`3^(2)` ×
`5^(1)`
