Given numbers are 878, 690, 863, 724

The list of prime factors of all numbers are

Prime factors of 878 are 2 x 439

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 863 are 863

Prime factors of 724 are 2 x 2 x 181

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

Given numbers are 878, 690, 863, 724

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

Apply this formula for all numbers.

Step1:

LCM(878, 690) = 302910

GCD(878, 690) = ( 878 x 690 ) / 302910

= 878 / 690

= 878

Step2:

LCM(2, 863) = 1726

GCD(2, 863) = ( 2 x 863 ) / 1726

= 2 / 863

= 2

Step3:

LCM(1, 724) = 724

GCD(1, 724) = ( 1 x 724 ) / 724

= 1 / 724

= 1

So, Greatest Common Divisor of 878, 690, 863, 724 is 1
