Given numbers are 847, 280, 805, 338

The list of prime factors of all numbers are

Prime factors of 847 are 7 x 11 x 11

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 805 are 5 x 7 x 23

Prime factors of 338 are 2 x 13 x 13

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

Given numbers are 847, 280, 805, 338

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

Apply this formula for all numbers.

Step1:

LCM(847, 280) = 33880

GCD(847, 280) = ( 847 x 280 ) / 33880

= 847 / 280

= 847

Step2:

LCM(7, 805) = 805

GCD(7, 805) = ( 7 x 805 ) / 805

= 7 / 805

= 7

Step3:

LCM(7, 338) = 2366

GCD(7, 338) = ( 7 x 338 ) / 2366

= 7 / 338

= 7

So, Greatest Common Divisor of 847, 280, 805, 338 is 1
