Given numbers are 847, 646, 390, 838

The list of prime factors of all numbers are

Prime factors of 847 are 7 x 11 x 11

Prime factors of 646 are 2 x 17 x 19

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 838 are 2 x 419

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

Given numbers are 847, 646, 390, 838

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

Apply this formula for all numbers.

Step1:

LCM(847, 646) = 547162

GCD(847, 646) = ( 847 x 646 ) / 547162

= 847 / 646

= 847

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 847, 646, 390, 838 is 1
