Given numbers are 393, 630, 639, 812

The list of prime factors of all numbers are

Prime factors of 393 are 3 x 131

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 639 are 3 x 3 x 71

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 393, 630, 639, 812

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

Apply this formula for all numbers.

Step1:

LCM(393, 630) = 82530

GCD(393, 630) = ( 393 x 630 ) / 82530

= 393 / 630

= 393

Step2:

LCM(3, 639) = 639

GCD(3, 639) = ( 3 x 639 ) / 639

= 3 / 639

= 3

Step3:

LCM(3, 812) = 2436

GCD(3, 812) = ( 3 x 812 ) / 2436

= 3 / 812

= 3

So, Greatest Common Divisor of 393, 630, 639, 812 is 1
