We found the divisors of 243, 151, 637, 248 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 243, 151, 637, 248 is 1.

Therefore, GCD of numbers 243, 151, 637, 248 is 1

Given Input Data is 243, 151, 637, 248

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

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

Prime Factorization of 151 is 151

Prime Factorization of 637 is 7 x 7 x 13

Prime Factorization of 248 is 2 x 2 x 2 x 31

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(243, 151) = 36693

GCD(243, 151) = ( 243 x 151 ) / 36693

GCD(243, 151) = 36693 / 36693

GCD(243, 151) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 637

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

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

GCD(1, 637) = 637 / 637

GCD(1, 637) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 248

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

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

GCD(1, 248) = 248 / 248

GCD(1, 248) = 1

GCD of 243, 151, 637, 248 is 1
