We found the divisors of 641, 490, 61, 184 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 641, 490, 61, 184 is 1.

Therefore, GCD of numbers 641, 490, 61, 184 is 1

Given Input Data is 641, 490, 61, 184

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

Prime Factorization of 641 is 641

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 61 is 61

Prime Factorization of 184 is 2 x 2 x 2 x 23

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(641, 490) = 314090

GCD(641, 490) = ( 641 x 490 ) / 314090

GCD(641, 490) = 314090 / 314090

GCD(641, 490) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 184

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

LCM(1, 184) = 184

GCD(1, 184) = ( 1 x 184 ) / 184

GCD(1, 184) = 184 / 184

GCD(1, 184) = 1

GCD of 641, 490, 61, 184 is 1
