Given Input Data is 615, 858, 726, 311

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 726 is 2 x 3 x 11 x 11

Prime Factorization of 311 is 311

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(615, 858) = 175890

GCD(615, 858) = ( 615 x 858 ) / 175890

GCD(615, 858) = 527670 / 175890

GCD(615, 858) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 726

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

LCM(3, 726) = 726

GCD(3, 726) = ( 3 x 726 ) / 726

GCD(3, 726) = 2178 / 726

GCD(3, 726) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 311

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

LCM(3, 311) = 933

GCD(3, 311) = ( 3 x 311 ) / 933

GCD(3, 311) = 933 / 933

GCD(3, 311) = 1

GCD of 615, 858, 726, 311 is 1

Here are some samples of GCD of Numbers calculations.

• GCD of 931, 802, 919, 260
