Given numbers are 434, 644, 429, 812

The list of prime factors of all numbers are

Prime factors of 434 are 2 x 7 x 31

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 429 are 3 x 11 x 13

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

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

Given numbers are 434, 644, 429, 812

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

Apply this formula for all numbers.

Step1:

LCM(434, 644) = 19964

GCD(434, 644) = ( 434 x 644 ) / 19964

= 434 / 644

= 434

Step2:

LCM(14, 429) = 6006

GCD(14, 429) = ( 14 x 429 ) / 6006

= 14 / 429

= 14

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 434, 644, 429, 812 is 1
