Greatest Common Divisior
We found the divisors of 177, 755, 643 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 177, 755, 643 is 1.
Therefore, GCD of numbers 177, 755, 643 is 1
Given Input Data is 177, 755, 643
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 177 is 3 x 59
Prime Factorization of 755 is 5 x 151
Prime Factorization of 643 is 643
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(177, 755) = 133635
GCD(177, 755) = ( 177 x 755 ) / 133635
GCD(177, 755) = 133635 / 133635
GCD(177, 755) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 643
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
GCD(1, 643) = 643 / 643
GCD(1, 643) = 1
GCD of 177, 755, 643 is 1
