Given numbers are 870, 681, 609, 154

The list of prime factors of all numbers are

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

Prime factors of 681 are 3 x 227

Prime factors of 609 are 3 x 7 x 29

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 870, 681, 609, 154

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

Apply this formula for all numbers.

Step1:

LCM(870, 681) = 197490

GCD(870, 681) = ( 870 x 681 ) / 197490

= 870 / 681

= 870

Step2:

LCM(3, 609) = 609

GCD(3, 609) = ( 3 x 609 ) / 609

= 3 / 609

= 3

Step3:

LCM(3, 154) = 462

GCD(3, 154) = ( 3 x 154 ) / 462

= 3 / 154

= 3

So, Greatest Common Divisor of 870, 681, 609, 154 is 1
