We found the divisors of 220, 221, 237, 949 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 220, 221, 237, 949 is 1.

Therefore, GCD of numbers 220, 221, 237, 949 is 1

Given Input Data is 220, 221, 237, 949

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

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

Prime Factorization of 221 is 13 x 17

Prime Factorization of 237 is 3 x 79

Prime Factorization of 949 is 13 x 73

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(220, 221) = 48620

GCD(220, 221) = ( 220 x 221 ) / 48620

GCD(220, 221) = 48620 / 48620

GCD(220, 221) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 237

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

LCM(1, 237) = 237

GCD(1, 237) = ( 1 x 237 ) / 237

GCD(1, 237) = 237 / 237

GCD(1, 237) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 949

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

LCM(1, 949) = 949

GCD(1, 949) = ( 1 x 949 ) / 949

GCD(1, 949) = 949 / 949

GCD(1, 949) = 1

GCD of 220, 221, 237, 949 is 1
