Given numbers are 863, 840, 298, 870

The list of prime factors of all numbers are

Prime factors of 863 are 863

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

Prime factors of 298 are 2 x 149

Prime factors of 870 are 2 x 3 x 5 x 29

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

Given numbers are 863, 840, 298, 870

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

Apply this formula for all numbers.

Step1:

LCM(863, 840) = 724920

GCD(863, 840) = ( 863 x 840 ) / 724920

= 863 / 840

= 863

Step2:

LCM(1, 298) = 298

GCD(1, 298) = ( 1 x 298 ) / 298

= 1 / 298

= 1

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 863, 840, 298, 870 is 1
