The list of prime factors of all numbers are

Prime factors of 847 are 7 x 11 x 11

Prime factors of 238 are 2 x 7 x 17

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 992 are 2 x 2 x 2 x 2 x 2 x 31

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

Given numbers are 847, 238, 640, 992

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

Apply this formula for all numbers.

Step1:

LCM(847, 238) = 28798

GCD(847, 238) = ( 847 x 238 ) / 28798

= 847 / 238

= 847

Step2:

LCM(7, 640) = 4480

GCD(7, 640) = ( 7 x 640 ) / 4480

= 7 / 640

= 7

Step3:

LCM(1, 992) = 992

GCD(1, 992) = ( 1 x 992 ) / 992

= 1 / 992

= 1

So, Greatest Common Divisor of 847, 238, 640, 992 is 1
