Given numbers are 640, 605, 308, 922

The list of prime factors of all numbers are

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

Prime factors of 605 are 5 x 11 x 11

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 922 are 2 x 461

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

Given numbers are 640, 605, 308, 922

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

Apply this formula for all numbers.

Step1:

LCM(640, 605) = 77440

GCD(640, 605) = ( 640 x 605 ) / 77440

= 640 / 605

= 640

Step2:

LCM(5, 308) = 1540

GCD(5, 308) = ( 5 x 308 ) / 1540

= 5 / 308

= 5

Step3:

LCM(1, 922) = 922

GCD(1, 922) = ( 1 x 922 ) / 922

= 1 / 922

= 1

So, Greatest Common Divisor of 640, 605, 308, 922 is 1
