Given numbers are 180, 664, 639, 974

The list of prime factors of all numbers are

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 639 are 3 x 3 x 71

Prime factors of 974 are 2 x 487

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

Given numbers are 180, 664, 639, 974

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

Apply this formula for all numbers.

Step1:

LCM(180, 664) = 29880

GCD(180, 664) = ( 180 x 664 ) / 29880

= 180 / 664

= 180

Step2:

LCM(4, 639) = 2556

GCD(4, 639) = ( 4 x 639 ) / 2556

= 4 / 639

= 4

Step3:

LCM(1, 974) = 974

GCD(1, 974) = ( 1 x 974 ) / 974

= 1 / 974

= 1

So, Greatest Common Divisor of 180, 664, 639, 974 is 1
