Given numbers are 398, 250, 646, 547

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

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

Prime factors of 646 are 2 x 17 x 19

Prime factors of 547 are 547

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

Given numbers are 398, 250, 646, 547

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

Apply this formula for all numbers.

Step1:

LCM(398, 250) = 49750

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

= 398 / 250

= 398

Step2:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

Step3:

LCM(2, 547) = 1094

GCD(2, 547) = ( 2 x 547 ) / 1094

= 2 / 547

= 2

So, Greatest Common Divisor of 398, 250, 646, 547 is 1
