Given numbers are 260, 155, 672, 129

The list of prime factors of all numbers are

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 155 are 5 x 31

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 129 are 3 x 43

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

Given numbers are 260, 155, 672, 129

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

Apply this formula for all numbers.

Step1:

LCM(260, 155) = 8060

GCD(260, 155) = ( 260 x 155 ) / 8060

= 260 / 155

= 260

Step2:

LCM(5, 672) = 3360

GCD(5, 672) = ( 5 x 672 ) / 3360

= 5 / 672

= 5

Step3:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 260, 155, 672, 129 is 1
