We found the divisors of 141, 636, 61, 245 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 141, 636, 61, 245 is 1.

Therefore, GCD of numbers 141, 636, 61, 245 is 1

Given Input Data is 141, 636, 61, 245

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

Prime Factorization of 141 is 3 x 47

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 61 is 61

Prime Factorization of 245 is 5 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(141, 636) = 29892

GCD(141, 636) = ( 141 x 636 ) / 29892

GCD(141, 636) = 89676 / 29892

GCD(141, 636) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 61

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

LCM(3, 61) = 183

GCD(3, 61) = ( 3 x 61 ) / 183

GCD(3, 61) = 183 / 183

GCD(3, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 245

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

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

GCD(1, 245) = 245 / 245

GCD(1, 245) = 1

GCD of 141, 636, 61, 245 is 1
