Given numbers are 639, 476, 745, 612

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 745 are 5 x 149

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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

Given numbers are 639, 476, 745, 612

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

Apply this formula for all numbers.

Step1:

LCM(639, 476) = 304164

GCD(639, 476) = ( 639 x 476 ) / 304164

= 639 / 476

= 639

Step2:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

Step3:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

So, Greatest Common Divisor of 639, 476, 745, 612 is 1
