Given numbers are 171, 250, 420, 260

The list of prime factors of all numbers are

Prime factors of 171 are 3 x 3 x 19

Prime factors of 250 are 2 x 5 x 5 x 5

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

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

Given numbers are 171, 250, 420, 260

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

Apply this formula for all numbers.

Step1:

LCM(171, 250) = 42750

GCD(171, 250) = ( 171 x 250 ) / 42750

= 171 / 250

= 171

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

So, Greatest Common Divisor of 171, 250, 420, 260 is 1
