Given numbers are 403, 872, 378, 429

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 872 are 2 x 2 x 2 x 109

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 429 are 3 x 11 x 13

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

Given numbers are 403, 872, 378, 429

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

Apply this formula for all numbers.

Step1:

LCM(403, 872) = 351416

GCD(403, 872) = ( 403 x 872 ) / 351416

= 403 / 872

= 403

Step2:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

Step3:

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

= 1 / 429

= 1

So, Greatest Common Divisor of 403, 872, 378, 429 is 1
