Given numbers are 855, 851, 428, 807

The list of prime factors of all numbers are

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

Prime factors of 851 are 23 x 37

Prime factors of 428 are 2 x 2 x 107

Prime factors of 807 are 3 x 269

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

Given numbers are 855, 851, 428, 807

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

Apply this formula for all numbers.

Step1:

LCM(855, 851) = 727605

GCD(855, 851) = ( 855 x 851 ) / 727605

= 855 / 851

= 855

Step2:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

Step3:

LCM(1, 807) = 807

GCD(1, 807) = ( 1 x 807 ) / 807

= 1 / 807

= 1

So, Greatest Common Divisor of 855, 851, 428, 807 is 1
