Given numbers are 863, 615, 690, 858

The list of prime factors of all numbers are

Prime factors of 863 are 863

Prime factors of 615 are 3 x 5 x 41

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

Prime factors of 858 are 2 x 3 x 11 x 13

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

Given numbers are 863, 615, 690, 858

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

Apply this formula for all numbers.

Step1:

LCM(863, 615) = 530745

GCD(863, 615) = ( 863 x 615 ) / 530745

= 863 / 615

= 863

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 863, 615, 690, 858 is 1
