Given numbers are 660, 672, 487, 165

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 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 487 are 487

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 660, 672, 487, 165

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

Apply this formula for all numbers.

Step1:

LCM(660, 672) = 36960

GCD(660, 672) = ( 660 x 672 ) / 36960

= 660 / 672

= 660

Step2:

LCM(12, 487) = 5844

GCD(12, 487) = ( 12 x 487 ) / 5844

= 12 / 487

= 12

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 660, 672, 487, 165 is 1
