Therefore, GCD of numbers 747, 830, 551 is 1

Given Input Data is 747, 830, 551

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

Prime Factorization of 747 is 3 x 3 x 83

Prime Factorization of 830 is 2 x 5 x 83

Prime Factorization of 551 is 19 x 29

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(747, 830) = 7470

GCD(747, 830) = ( 747 x 830 ) / 7470

GCD(747, 830) = 620010 / 7470

GCD(747, 830) = 83

Step2:

Here we consider the GCD from the above i.e. 83 as first number and the next as 551

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

LCM(83, 551) = 45733

GCD(83, 551) = ( 83 x 551 ) / 45733

GCD(83, 551) = 45733 / 45733

GCD(83, 551) = 1

GCD of 747, 830, 551 is 1
