We found the divisors of 642, 193, 73, 550 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 642, 193, 73, 550 is 1.

Therefore, GCD of numbers 642, 193, 73, 550 is 1

Given Input Data is 642, 193, 73, 550

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

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 193 is 193

Prime Factorization of 73 is 73

Prime Factorization of 550 is 2 x 5 x 5 x 11

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(642, 193) = 123906

GCD(642, 193) = ( 642 x 193 ) / 123906

GCD(642, 193) = 123906 / 123906

GCD(642, 193) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 73

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

LCM(1, 73) = 73

GCD(1, 73) = ( 1 x 73 ) / 73

GCD(1, 73) = 73 / 73

GCD(1, 73) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 550

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

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

GCD(1, 550) = 550 / 550

GCD(1, 550) = 1

GCD of 642, 193, 73, 550 is 1
