Given numbers are 660, 278, 756, 125

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 278 are 2 x 139

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 125 are 5 x 5 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 660, 278, 756, 125

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(660, 278) = 91740

GCD(660, 278) = ( 660 x 278 ) / 91740

= 660 / 278

= 660

Step2:

LCM(2, 756) = 756

GCD(2, 756) = ( 2 x 756 ) / 756

= 2 / 756

= 2

Step3:

LCM(2, 125) = 250

GCD(2, 125) = ( 2 x 125 ) / 250

= 2 / 125

= 2

So, Greatest Common Divisor of 660, 278, 756, 125 is 1
