Given numbers are 431, 812, 621, 126

The list of prime factors of all numbers are

Prime factors of 431 are 431

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 126 are 2 x 3 x 3 x 7

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

Given numbers are 431, 812, 621, 126

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

Apply this formula for all numbers.

Step1:

LCM(431, 812) = 349972

GCD(431, 812) = ( 431 x 812 ) / 349972

= 431 / 812

= 431

Step2:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 431, 812, 621, 126 is 1
