Therefore, GCD of numbers 783, 609, 89, 655 is 1

Given Input Data is 783, 609, 89, 655

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

Prime Factorization of 783 is 3 x 3 x 3 x 29

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 89 is 89

Prime Factorization of 655 is 5 x 131

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(783, 609) = 5481

GCD(783, 609) = ( 783 x 609 ) / 5481

GCD(783, 609) = 476847 / 5481

GCD(783, 609) = 87

Step2:

Here we consider the GCD from the above i.e. 87 as first number and the next as 89

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

LCM(87, 89) = 7743

GCD(87, 89) = ( 87 x 89 ) / 7743

GCD(87, 89) = 7743 / 7743

GCD(87, 89) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 655

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

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

GCD(1, 655) = 655 / 655

GCD(1, 655) = 1

GCD of 783, 609, 89, 655 is 1
