Given numbers are 435, 645, 271, 172

The list of prime factors of all numbers are

Prime factors of 435 are 3 x 5 x 29

Prime factors of 645 are 3 x 5 x 43

Prime factors of 271 are 271

Prime factors of 172 are 2 x 2 x 43

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

Given numbers are 435, 645, 271, 172

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

Apply this formula for all numbers.

Step1:

LCM(435, 645) = 18705

GCD(435, 645) = ( 435 x 645 ) / 18705

= 435 / 645

= 435

Step2:

LCM(15, 271) = 4065

GCD(15, 271) = ( 15 x 271 ) / 4065

= 15 / 271

= 15

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 435, 645, 271, 172 is 1
