We found the divisors of 371, 221, 70, 441 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 371, 221, 70, 441 is 1.

Therefore, GCD of numbers 371, 221, 70, 441 is 1

Given Input Data is 371, 221, 70, 441

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

Prime Factorization of 371 is 7 x 53

Prime Factorization of 221 is 13 x 17

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 441 is 3 x 3 x 7 x 7

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(371, 221) = 81991

GCD(371, 221) = ( 371 x 221 ) / 81991

GCD(371, 221) = 81991 / 81991

GCD(371, 221) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 70

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

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

GCD(1, 70) = 70 / 70

GCD(1, 70) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 441

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

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

GCD(1, 441) = 441 / 441

GCD(1, 441) = 1

GCD of 371, 221, 70, 441 is 1
