Given numbers are 117, 640, 840, 358

The list of prime factors of all numbers are

Prime factors of 117 are 3 x 3 x 13

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 358 are 2 x 179

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

Given numbers are 117, 640, 840, 358

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

Apply this formula for all numbers.

Step1:

LCM(117, 640) = 74880

GCD(117, 640) = ( 117 x 640 ) / 74880

= 117 / 640

= 117

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 358) = 358

GCD(1, 358) = ( 1 x 358 ) / 358

= 1 / 358

= 1

So, Greatest Common Divisor of 117, 640, 840, 358 is 1
