Given numbers are 943, 656, 660, 921

The list of prime factors of all numbers are

Prime factors of 943 are 23 x 41

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Prime factors of 921 are 3 x 307

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

Given numbers are 943, 656, 660, 921

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

Apply this formula for all numbers.

Step1:

LCM(943, 656) = 15088

GCD(943, 656) = ( 943 x 656 ) / 15088

= 943 / 656

= 943

Step2:

LCM(41, 660) = 27060

GCD(41, 660) = ( 41 x 660 ) / 27060

= 41 / 660

= 41

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 943, 656, 660, 921 is 1
