Given numbers are 870, 404, 778, 169

The list of prime factors of all numbers are

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

Prime factors of 404 are 2 x 2 x 101

Prime factors of 778 are 2 x 389

Prime factors of 169 are 13 x 13

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

Given numbers are 870, 404, 778, 169

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

Apply this formula for all numbers.

Step1:

LCM(870, 404) = 175740

GCD(870, 404) = ( 870 x 404 ) / 175740

= 870 / 404

= 870

Step2:

LCM(2, 778) = 778

GCD(2, 778) = ( 2 x 778 ) / 778

= 2 / 778

= 2

Step3:

LCM(2, 169) = 338

GCD(2, 169) = ( 2 x 169 ) / 338

= 2 / 169

= 2

So, Greatest Common Divisor of 870, 404, 778, 169 is 1
