Given numbers are 312, 447, 805, 556

The list of prime factors of all numbers are

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 447 are 3 x 149

Prime factors of 805 are 5 x 7 x 23

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 312, 447, 805, 556

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

Apply this formula for all numbers.

Step1:

LCM(312, 447) = 46488

GCD(312, 447) = ( 312 x 447 ) / 46488

= 312 / 447

= 312

Step2:

LCM(3, 805) = 2415

GCD(3, 805) = ( 3 x 805 ) / 2415

= 3 / 805

= 3

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 312, 447, 805, 556 is 1
