Given numbers are 630, 643, 812, 800

The list of prime factors of all numbers are

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

Prime factors of 643 are 643

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

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 630, 643, 812, 800

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

Apply this formula for all numbers.

Step1:

LCM(630, 643) = 405090

GCD(630, 643) = ( 630 x 643 ) / 405090

= 630 / 643

= 630

Step2:

LCM(1, 812) = 812

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

= 1 / 812

= 1

Step3:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

So, Greatest Common Divisor of 630, 643, 812, 800 is 1
