Given numbers are 870, 669, 856, 158

The list of prime factors of all numbers are

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

Prime factors of 669 are 3 x 223

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

Prime factors of 158 are 2 x 79

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

Given numbers are 870, 669, 856, 158

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

Apply this formula for all numbers.

Step1:

LCM(870, 669) = 194010

GCD(870, 669) = ( 870 x 669 ) / 194010

= 870 / 669

= 870

Step2:

LCM(3, 856) = 2568

GCD(3, 856) = ( 3 x 856 ) / 2568

= 3 / 856

= 3

Step3:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 870, 669, 856, 158 is 1
