Given numbers are 250, 170, 691, 380

The list of prime factors of all numbers are

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

Prime factors of 170 are 2 x 5 x 17

Prime factors of 691 are 691

Prime factors of 380 are 2 x 2 x 5 x 19

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

Given numbers are 250, 170, 691, 380

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

Apply this formula for all numbers.

Step1:

LCM(250, 170) = 4250

GCD(250, 170) = ( 250 x 170 ) / 4250

= 250 / 170

= 250

Step2:

LCM(10, 691) = 6910

GCD(10, 691) = ( 10 x 691 ) / 6910

= 10 / 691

= 10

Step3:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 250, 170, 691, 380 is 1
