Given numbers are 975, 814, 780, 817

The list of prime factors of all numbers are

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

Prime factors of 814 are 2 x 11 x 37

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 817 are 19 x 43

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

Given numbers are 975, 814, 780, 817

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

Apply this formula for all numbers.

Step1:

LCM(975, 814) = 793650

GCD(975, 814) = ( 975 x 814 ) / 793650

= 975 / 814

= 975

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

So, Greatest Common Divisor of 975, 814, 780, 817 is 1
