Given numbers are 771, 112, 447, 870

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 112 are 2 x 2 x 2 x 2 x 7

Prime factors of 447 are 3 x 149

Prime factors of 870 are 2 x 3 x 5 x 29

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

Given numbers are 771, 112, 447, 870

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

Apply this formula for all numbers.

Step1:

LCM(771, 112) = 86352

GCD(771, 112) = ( 771 x 112 ) / 86352

= 771 / 112

= 771

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 771, 112, 447, 870 is 1
