Given numbers are 129, 216, 290, 435

The list of prime factors of all numbers are

Prime factors of 129 are 3 x 43

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 290 are 2 x 5 x 29

Prime factors of 435 are 3 x 5 x 29

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

Given numbers are 129, 216, 290, 435

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

Apply this formula for all numbers.

Step1:

LCM(129, 216) = 9288

GCD(129, 216) = ( 129 x 216 ) / 9288

= 129 / 216

= 129

Step2:

LCM(3, 290) = 870

GCD(3, 290) = ( 3 x 290 ) / 870

= 3 / 290

= 3

Step3:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

So, Greatest Common Divisor of 129, 216, 290, 435 is 1
