Given numbers are 521, 640, 942, 966

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 942 are 2 x 3 x 157

Prime factors of 966 are 2 x 3 x 7 x 23

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

Given numbers are 521, 640, 942, 966

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

Apply this formula for all numbers.

Step1:

LCM(521, 640) = 333440

GCD(521, 640) = ( 521 x 640 ) / 333440

= 521 / 640

= 521

Step2:

LCM(1, 942) = 942

GCD(1, 942) = ( 1 x 942 ) / 942

= 1 / 942

= 1

Step3:

LCM(1, 966) = 966

GCD(1, 966) = ( 1 x 966 ) / 966

= 1 / 966

= 1

So, Greatest Common Divisor of 521, 640, 942, 966 is 1
