Therefore, GCD of numbers 665, 406, 221, 892 is 1

Given Input Data is 665, 406, 221, 892

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

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 221 is 13 x 17

Prime Factorization of 892 is 2 x 2 x 223

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(665, 406) = 38570

GCD(665, 406) = ( 665 x 406 ) / 38570

GCD(665, 406) = 269990 / 38570

GCD(665, 406) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 221

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

LCM(7, 221) = 1547

GCD(7, 221) = ( 7 x 221 ) / 1547

GCD(7, 221) = 1547 / 1547

GCD(7, 221) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 892

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

LCM(1, 892) = 892

GCD(1, 892) = ( 1 x 892 ) / 892

GCD(1, 892) = 892 / 892

GCD(1, 892) = 1

GCD of 665, 406, 221, 892 is 1
