Given numbers are 310, 638, 975, 905

The list of prime factors of all numbers are

Prime factors of 310 are 2 x 5 x 31

Prime factors of 638 are 2 x 11 x 29

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

Prime factors of 905 are 5 x 181

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

Given numbers are 310, 638, 975, 905

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

Apply this formula for all numbers.

Step1:

LCM(310, 638) = 98890

GCD(310, 638) = ( 310 x 638 ) / 98890

= 310 / 638

= 310

Step2:

LCM(2, 975) = 1950

GCD(2, 975) = ( 2 x 975 ) / 1950

= 2 / 975

= 2

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 310, 638, 975, 905 is 1
