Therefore, GCD of numbers 486, 621, 362, 680 is 1

Given Input Data is 486, 621, 362, 680

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 621 is 3 x 3 x 3 x 23

Prime Factorization of 362 is 2 x 181

Prime Factorization of 680 is 2 x 2 x 2 x 5 x 17

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, 621) = 11178

GCD(486, 621) = ( 486 x 621 ) / 11178

GCD(486, 621) = 301806 / 11178

GCD(486, 621) = 27

Step2:

Here we consider the GCD from the above i.e. 27 as first number and the next as 362

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

LCM(27, 362) = 9774

GCD(27, 362) = ( 27 x 362 ) / 9774

GCD(27, 362) = 9774 / 9774

GCD(27, 362) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 680

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

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

GCD(1, 680) = 680 / 680

GCD(1, 680) = 1

GCD of 486, 621, 362, 680 is 1
