Given numbers are 688, 840, 863, 385

The list of prime factors of all numbers are

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Prime factors of 863 are 863

Prime factors of 385 are 5 x 7 x 11

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

Given numbers are 688, 840, 863, 385

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

Apply this formula for all numbers.

Step1:

LCM(688, 840) = 72240

GCD(688, 840) = ( 688 x 840 ) / 72240

= 688 / 840

= 688

Step2:

LCM(8, 863) = 6904

GCD(8, 863) = ( 8 x 863 ) / 6904

= 8 / 863

= 8

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 688, 840, 863, 385 is 1
