Given numbers are 640, 694, 736, 117

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 694 are 2 x 347

Prime factors of 736 are 2 x 2 x 2 x 2 x 2 x 23

Prime factors of 117 are 3 x 3 x 13

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

Given numbers are 640, 694, 736, 117

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

Apply this formula for all numbers.

Step1:

LCM(640, 694) = 222080

GCD(640, 694) = ( 640 x 694 ) / 222080

= 640 / 694

= 640

Step2:

LCM(2, 736) = 736

GCD(2, 736) = ( 2 x 736 ) / 736

= 2 / 736

= 2

Step3:

LCM(2, 117) = 234

GCD(2, 117) = ( 2 x 117 ) / 234

= 2 / 117

= 2

So, Greatest Common Divisor of 640, 694, 736, 117 is 1
