Given numbers are 345, 600, 117, 640

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 600 are 2 x 2 x 2 x 3 x 5 x 5

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

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

Given numbers are 345, 600, 117, 640

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

Apply this formula for all numbers.

Step1:

LCM(345, 600) = 13800

GCD(345, 600) = ( 345 x 600 ) / 13800

= 345 / 600

= 345

Step2:

LCM(15, 117) = 585

GCD(15, 117) = ( 15 x 117 ) / 585

= 15 / 117

= 15

Step3:

LCM(3, 640) = 1920

GCD(3, 640) = ( 3 x 640 ) / 1920

= 3 / 640

= 3

So, Greatest Common Divisor of 345, 600, 117, 640 is 1
