Therefore, GCD of numbers 411, 806, 87, 160 is 1

Given Input Data is 411, 806, 87, 160

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

Prime Factorization of 411 is 3 x 137

Prime Factorization of 806 is 2 x 13 x 31

Prime Factorization of 87 is 3 x 29

Prime Factorization of 160 is 2 x 2 x 2 x 2 x 2 x 5

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(411, 806) = 331266

GCD(411, 806) = ( 411 x 806 ) / 331266

GCD(411, 806) = 331266 / 331266

GCD(411, 806) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 87

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

LCM(1, 87) = 87

GCD(1, 87) = ( 1 x 87 ) / 87

GCD(1, 87) = 87 / 87

GCD(1, 87) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 160

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

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

GCD(1, 160) = 160 / 160

GCD(1, 160) = 1

GCD of 411, 806, 87, 160 is 1
