Given numbers are 155, 870, 166, 631

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

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

Prime factors of 166 are 2 x 83

Prime factors of 631 are 631

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

Given numbers are 155, 870, 166, 631

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

Apply this formula for all numbers.

Step1:

LCM(155, 870) = 26970

GCD(155, 870) = ( 155 x 870 ) / 26970

= 155 / 870

= 155

Step2:

LCM(5, 166) = 830

GCD(5, 166) = ( 5 x 166 ) / 830

= 5 / 166

= 5

Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 155, 870, 166, 631 is 1
