Therefore, GCD of numbers 431, 261, 373, 220 is 1

Given Input Data is 431, 261, 373, 220

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

Prime Factorization of 431 is 431

Prime Factorization of 261 is 3 x 3 x 29

Prime Factorization of 373 is 373

Prime Factorization of 220 is 2 x 2 x 5 x 11

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(431, 261) = 112491

GCD(431, 261) = ( 431 x 261 ) / 112491

GCD(431, 261) = 112491 / 112491

GCD(431, 261) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 373

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

LCM(1, 373) = 373

GCD(1, 373) = ( 1 x 373 ) / 373

GCD(1, 373) = 373 / 373

GCD(1, 373) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 220

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

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

GCD(1, 220) = 220 / 220

GCD(1, 220) = 1

GCD of 431, 261, 373, 220 is 1
