Given numbers are 812, 828, 647, 835

The list of prime factors of all numbers are

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

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 647 are 647

Prime factors of 835 are 5 x 167

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

Given numbers are 812, 828, 647, 835

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

Apply this formula for all numbers.

Step1:

LCM(812, 828) = 168084

GCD(812, 828) = ( 812 x 828 ) / 168084

= 812 / 828

= 812

Step2:

LCM(4, 647) = 2588

GCD(4, 647) = ( 4 x 647 ) / 2588

= 4 / 647

= 4

Step3:

LCM(1, 835) = 835

GCD(1, 835) = ( 1 x 835 ) / 835

= 1 / 835

= 1

So, Greatest Common Divisor of 812, 828, 647, 835 is 1
