Therefore, GCD of numbers 877, 550, 18, 123 is 1

Given Input Data is 877, 550, 18, 123

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

Prime Factorization of 877 is 877

Prime Factorization of 550 is 2 x 5 x 5 x 11

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 123 is 3 x 41

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(877, 550) = 482350

GCD(877, 550) = ( 877 x 550 ) / 482350

GCD(877, 550) = 482350 / 482350

GCD(877, 550) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 18

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

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

GCD(1, 18) = 18 / 18

GCD(1, 18) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 123

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

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

GCD(1, 123) = 123 / 123

GCD(1, 123) = 1

GCD of 877, 550, 18, 123 is 1
