Given numbers are 826, 815, 855, 812

The list of prime factors of all numbers are

Prime factors of 826 are 2 x 7 x 59

Prime factors of 815 are 5 x 163

Prime factors of 855 are 3 x 3 x 5 x 19

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 826, 815, 855, 812

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

Apply this formula for all numbers.

Step1:

LCM(826, 815) = 673190

GCD(826, 815) = ( 826 x 815 ) / 673190

= 826 / 815

= 826

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 812) = 812

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

= 1 / 812

= 1

So, Greatest Common Divisor of 826, 815, 855, 812 is 1
