Therefore, GCD of numbers 740, 640, 427, 161 is 1

Given Input Data is 740, 640, 427, 161

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

Prime Factorization of 740 is 2 x 2 x 5 x 37

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 427 is 7 x 61

Prime Factorization of 161 is 7 x 23

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(740, 640) = 23680

GCD(740, 640) = ( 740 x 640 ) / 23680

GCD(740, 640) = 473600 / 23680

GCD(740, 640) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 427

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

LCM(20, 427) = 8540

GCD(20, 427) = ( 20 x 427 ) / 8540

GCD(20, 427) = 8540 / 8540

GCD(20, 427) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 161

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

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

GCD(1, 161) = 161 / 161

GCD(1, 161) = 1

GCD of 740, 640, 427, 161 is 1
