Given numbers are 494, 416, 137, 640

The list of prime factors of all numbers are

Prime factors of 494 are 2 x 13 x 19

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 137 are 137

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 494, 416, 137, 640

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

Apply this formula for all numbers.

Step1:

LCM(494, 416) = 7904

GCD(494, 416) = ( 494 x 416 ) / 7904

= 494 / 416

= 494

Step2:

LCM(26, 137) = 3562

GCD(26, 137) = ( 26 x 137 ) / 3562

= 26 / 137

= 26

Step3:

LCM(1, 640) = 640

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

= 1 / 640

= 1

So, Greatest Common Divisor of 494, 416, 137, 640 is 1
