Given numbers are 250, 398, 519, 690

The list of prime factors of all numbers are

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

Prime factors of 398 are 2 x 199

Prime factors of 519 are 3 x 173

Prime factors of 690 are 2 x 3 x 5 x 23

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

Given numbers are 250, 398, 519, 690

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

Apply this formula for all numbers.

Step1:

LCM(250, 398) = 49750

GCD(250, 398) = ( 250 x 398 ) / 49750

= 250 / 398

= 250

Step2:

LCM(2, 519) = 1038

GCD(2, 519) = ( 2 x 519 ) / 1038

= 2 / 519

= 2

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 250, 398, 519, 690 is 1
