Given numbers are 639, 462, 948, 623

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 948 are 2 x 2 x 3 x 79

Prime factors of 623 are 7 x 89

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

Given numbers are 639, 462, 948, 623

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

Apply this formula for all numbers.

Step1:

LCM(639, 462) = 98406

GCD(639, 462) = ( 639 x 462 ) / 98406

= 639 / 462

= 639

Step2:

LCM(3, 948) = 948

GCD(3, 948) = ( 3 x 948 ) / 948

= 3 / 948

= 3

Step3:

LCM(3, 623) = 1869

GCD(3, 623) = ( 3 x 623 ) / 1869

= 3 / 623

= 3

So, Greatest Common Divisor of 639, 462, 948, 623 is 1
