Therefore, GCD of numbers 268, 278, 190, 181 is 1

Given Input Data is 268, 278, 190, 181

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

Prime Factorization of 268 is 2 x 2 x 67

Prime Factorization of 278 is 2 x 139

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 181 is 181

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(268, 278) = 37252

GCD(268, 278) = ( 268 x 278 ) / 37252

GCD(268, 278) = 74504 / 37252

GCD(268, 278) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 190

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

LCM(2, 190) = 190

GCD(2, 190) = ( 2 x 190 ) / 190

GCD(2, 190) = 380 / 190

GCD(2, 190) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 181

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

LCM(2, 181) = 362

GCD(2, 181) = ( 2 x 181 ) / 362

GCD(2, 181) = 362 / 362

GCD(2, 181) = 1

GCD of 268, 278, 190, 181 is 1
