Given numbers are 840, 969, 256, 847

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 969 are 3 x 17 x 19

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 847 are 7 x 11 x 11

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

Given numbers are 840, 969, 256, 847

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

Apply this formula for all numbers.

Step1:

LCM(840, 969) = 271320

GCD(840, 969) = ( 840 x 969 ) / 271320

= 840 / 969

= 840

Step2:

LCM(3, 256) = 768

GCD(3, 256) = ( 3 x 256 ) / 768

= 3 / 256

= 3

Step3:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

So, Greatest Common Divisor of 840, 969, 256, 847 is 1
