Therefore, GCD of numbers 845, 143, 609, 931 is 1

Given Input Data is 845, 143, 609, 931

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

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 143 is 11 x 13

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 931 is 7 x 7 x 19

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(845, 143) = 9295

GCD(845, 143) = ( 845 x 143 ) / 9295

GCD(845, 143) = 120835 / 9295

GCD(845, 143) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 609

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

LCM(13, 609) = 7917

GCD(13, 609) = ( 13 x 609 ) / 7917

GCD(13, 609) = 7917 / 7917

GCD(13, 609) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 931

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

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

GCD(1, 931) = 931 / 931

GCD(1, 931) = 1

GCD of 845, 143, 609, 931 is 1
