Given numbers are 408, 129, 748, 435

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 129 are 3 x 43

Prime factors of 748 are 2 x 2 x 11 x 17

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 408, 129, 748, 435

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

Apply this formula for all numbers.

Step1:

LCM(408, 129) = 17544

GCD(408, 129) = ( 408 x 129 ) / 17544

= 408 / 129

= 408

Step2:

LCM(3, 748) = 2244

GCD(3, 748) = ( 3 x 748 ) / 2244

= 3 / 748

= 3

Step3:

LCM(1, 435) = 435

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

= 1 / 435

= 1

So, Greatest Common Divisor of 408, 129, 748, 435 is 1
