Given numbers are 855, 828, 154, 451

The list of prime factors of all numbers are

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

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

Prime factors of 154 are 2 x 7 x 11

Prime factors of 451 are 11 x 41

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

Given numbers are 855, 828, 154, 451

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

Apply this formula for all numbers.

Step1:

LCM(855, 828) = 78660

GCD(855, 828) = ( 855 x 828 ) / 78660

= 855 / 828

= 855

Step2:

LCM(9, 154) = 1386

GCD(9, 154) = ( 9 x 154 ) / 1386

= 9 / 154

= 9

Step3:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

So, Greatest Common Divisor of 855, 828, 154, 451 is 1
