Given Input Data is 858, 636, 340, 893

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

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 340 is 2 x 2 x 5 x 17

Prime Factorization of 893 is 19 x 47

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(858, 636) = 90948

GCD(858, 636) = ( 858 x 636 ) / 90948

GCD(858, 636) = 545688 / 90948

GCD(858, 636) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 340

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

LCM(6, 340) = 1020

GCD(6, 340) = ( 6 x 340 ) / 1020

GCD(6, 340) = 2040 / 1020

GCD(6, 340) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 893

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

LCM(2, 893) = 1786

GCD(2, 893) = ( 2 x 893 ) / 1786

GCD(2, 893) = 1786 / 1786

GCD(2, 893) = 1

GCD of 858, 636, 340, 893 is 1
