Given numbers are 931, 509, 644, 774

The list of prime factors of all numbers are

Prime factors of 931 are 7 x 7 x 19

Prime factors of 509 are 509

Prime factors of 644 are 2 x 2 x 7 x 23

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

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

Given numbers are 931, 509, 644, 774

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

Apply this formula for all numbers.

Step1:

LCM(931, 509) = 473879

GCD(931, 509) = ( 931 x 509 ) / 473879

= 931 / 509

= 931

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

= 1 / 774

= 1

So, Greatest Common Divisor of 931, 509, 644, 774 is 1
