Therefore, GCD of numbers 486, 963, 783, 665 is 1

Given Input Data is 486, 963, 783, 665

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

Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3

Prime Factorization of 963 is 3 x 3 x 107

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

Prime Factorization of 665 is 5 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(486, 963) = 52002

GCD(486, 963) = ( 486 x 963 ) / 52002

GCD(486, 963) = 468018 / 52002

GCD(486, 963) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 783

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

LCM(9, 783) = 783

GCD(9, 783) = ( 9 x 783 ) / 783

GCD(9, 783) = 7047 / 783

GCD(9, 783) = 9

Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 665

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

LCM(9, 665) = 5985

GCD(9, 665) = ( 9 x 665 ) / 5985

GCD(9, 665) = 5985 / 5985

GCD(9, 665) = 1

GCD of 486, 963, 783, 665 is 1
