Given numbers are 931, 791, 358, 646

The list of prime factors of all numbers are

Prime factors of 931 are 7 x 7 x 19

Prime factors of 791 are 7 x 113

Prime factors of 358 are 2 x 179

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 931, 791, 358, 646

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

Apply this formula for all numbers.

Step1:

LCM(931, 791) = 105203

GCD(931, 791) = ( 931 x 791 ) / 105203

= 931 / 791

= 931

Step2:

LCM(7, 358) = 2506

GCD(7, 358) = ( 7 x 358 ) / 2506

= 7 / 358

= 7

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 931, 791, 358, 646 is 1
