Given numbers are 863, 580, 646, 864

The list of prime factors of all numbers are

Prime factors of 863 are 863

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 646 are 2 x 17 x 19

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 863, 580, 646, 864

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

Apply this formula for all numbers.

Step1:

LCM(863, 580) = 500540

GCD(863, 580) = ( 863 x 580 ) / 500540

= 863 / 580

= 863

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

So, Greatest Common Divisor of 863, 580, 646, 864 is 1
