Given numbers are 461, 422, 620, 640

The list of prime factors of all numbers are

Prime factors of 461 are 461

Prime factors of 422 are 2 x 211

Prime factors of 620 are 2 x 2 x 5 x 31

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 461, 422, 620, 640

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

Apply this formula for all numbers.

Step1:

LCM(461, 422) = 194542

GCD(461, 422) = ( 461 x 422 ) / 194542

= 461 / 422

= 461

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 640) = 640

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

= 1 / 640

= 1

So, Greatest Common Divisor of 461, 422, 620, 640 is 1
