Given numbers are 645, 255, 429, 352

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 255 are 3 x 5 x 17

Prime factors of 429 are 3 x 11 x 13

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

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

Given numbers are 645, 255, 429, 352

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

Apply this formula for all numbers.

Step1:

LCM(645, 255) = 10965

GCD(645, 255) = ( 645 x 255 ) / 10965

= 645 / 255

= 645

Step2:

LCM(15, 429) = 2145

GCD(15, 429) = ( 15 x 429 ) / 2145

= 15 / 429

= 15

Step3:

LCM(3, 352) = 1056

GCD(3, 352) = ( 3 x 352 ) / 1056

= 3 / 352

= 3

So, Greatest Common Divisor of 645, 255, 429, 352 is 1
