Given numbers are 478, 856, 648, 427

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 427 are 7 x 61

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

Given numbers are 478, 856, 648, 427

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

Apply this formula for all numbers.

Step1:

LCM(478, 856) = 204584

GCD(478, 856) = ( 478 x 856 ) / 204584

= 478 / 856

= 478

Step2:

LCM(2, 648) = 648

GCD(2, 648) = ( 2 x 648 ) / 648

= 2 / 648

= 2

Step3:

LCM(2, 427) = 854

GCD(2, 427) = ( 2 x 427 ) / 854

= 2 / 427

= 2

So, Greatest Common Divisor of 478, 856, 648, 427 is 1
