Given numbers are 640, 798, 461, 157

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 798 are 2 x 3 x 7 x 19

Prime factors of 461 are 461

Prime factors of 157 are 157

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

Given numbers are 640, 798, 461, 157

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

Apply this formula for all numbers.

Step1:

LCM(640, 798) = 255360

GCD(640, 798) = ( 640 x 798 ) / 255360

= 640 / 798

= 640

Step2:

LCM(2, 461) = 922

GCD(2, 461) = ( 2 x 461 ) / 922

= 2 / 461

= 2

Step3:

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

= 1 / 157

= 1

So, Greatest Common Divisor of 640, 798, 461, 157 is 1
