Given Input Data is 390, 220, 997, 141

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

Prime Factorization of 390 is 2 x 3 x 5 x 13

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

Prime Factorization of 997 is 997

Prime Factorization of 141 is 3 x 47

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(390, 220) = 8580

GCD(390, 220) = ( 390 x 220 ) / 8580

GCD(390, 220) = 85800 / 8580

GCD(390, 220) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 997

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

LCM(10, 997) = 9970

GCD(10, 997) = ( 10 x 997 ) / 9970

GCD(10, 997) = 9970 / 9970

GCD(10, 997) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 141

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

LCM(1, 141) = 141

GCD(1, 141) = ( 1 x 141 ) / 141

GCD(1, 141) = 141 / 141

GCD(1, 141) = 1

GCD of 390, 220, 997, 141 is 1
