Given numbers are 398, 836, 408, 859

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 859 are 859

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

Given numbers are 398, 836, 408, 859

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

Apply this formula for all numbers.

Step1:

LCM(398, 836) = 166364

GCD(398, 836) = ( 398 x 836 ) / 166364

= 398 / 836

= 398

Step2:

LCM(2, 408) = 408

GCD(2, 408) = ( 2 x 408 ) / 408

= 2 / 408

= 2

Step3:

LCM(2, 859) = 1718

GCD(2, 859) = ( 2 x 859 ) / 1718

= 2 / 859

= 2

So, Greatest Common Divisor of 398, 836, 408, 859 is 1
