Given numbers are 921, 508, 370, 640

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 508 are 2 x 2 x 127

Prime factors of 370 are 2 x 5 x 37

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

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

Given numbers are 921, 508, 370, 640

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

Apply this formula for all numbers.

Step1:

LCM(921, 508) = 467868

GCD(921, 508) = ( 921 x 508 ) / 467868

= 921 / 508

= 921

Step2:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 921, 508, 370, 640 is 1
