Given numbers are 975, 620, 747, 638

The list of prime factors of all numbers are

Prime factors of 975 are 3 x 5 x 5 x 13

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 747 are 3 x 3 x 83

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 975, 620, 747, 638

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

Apply this formula for all numbers.

Step1:

LCM(975, 620) = 120900

GCD(975, 620) = ( 975 x 620 ) / 120900

= 975 / 620

= 975

Step2:

LCM(5, 747) = 3735

GCD(5, 747) = ( 5 x 747 ) / 3735

= 5 / 747

= 5

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 975, 620, 747, 638 is 1
