Given numbers are 640, 132, 917, 461

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 132 are 2 x 2 x 3 x 11

Prime factors of 917 are 7 x 131

Prime factors of 461 are 461

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

Given numbers are 640, 132, 917, 461

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

Apply this formula for all numbers.

Step1:

LCM(640, 132) = 21120

GCD(640, 132) = ( 640 x 132 ) / 21120

= 640 / 132

= 640

Step2:

LCM(4, 917) = 3668

GCD(4, 917) = ( 4 x 917 ) / 3668

= 4 / 917

= 4

Step3:

LCM(1, 461) = 461

GCD(1, 461) = ( 1 x 461 ) / 461

= 1 / 461

= 1

So, Greatest Common Divisor of 640, 132, 917, 461 is 1
