Given numbers are 870, 355, 581, 126

The list of prime factors of all numbers are

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

Prime factors of 355 are 5 x 71

Prime factors of 581 are 7 x 83

Prime factors of 126 are 2 x 3 x 3 x 7

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

Given numbers are 870, 355, 581, 126

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

Apply this formula for all numbers.

Step1:

LCM(870, 355) = 61770

GCD(870, 355) = ( 870 x 355 ) / 61770

= 870 / 355

= 870

Step2:

LCM(5, 581) = 2905

GCD(5, 581) = ( 5 x 581 ) / 2905

= 5 / 581

= 5

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 870, 355, 581, 126 is 1
