Given numbers are 257, 660, 828, 931

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 931 are 7 x 7 x 19

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

Given numbers are 257, 660, 828, 931

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

Apply this formula for all numbers.

Step1:

LCM(257, 660) = 169620

GCD(257, 660) = ( 257 x 660 ) / 169620

= 257 / 660

= 257

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

So, Greatest Common Divisor of 257, 660, 828, 931 is 1
