Given numbers are 975, 315, 774, 665

The list of prime factors of all numbers are

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

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 975, 315, 774, 665

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

Apply this formula for all numbers.

Step1:

LCM(975, 315) = 20475

GCD(975, 315) = ( 975 x 315 ) / 20475

= 975 / 315

= 975

Step2:

LCM(15, 774) = 3870

GCD(15, 774) = ( 15 x 774 ) / 3870

= 15 / 774

= 15

Step3:

LCM(3, 665) = 1995

GCD(3, 665) = ( 3 x 665 ) / 1995

= 3 / 665

= 3

So, Greatest Common Divisor of 975, 315, 774, 665 is 1
