1, 197
Greatest Common Divisior
We found the divisors of 207, 145, 777, 197 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 207, 145, 777, 197 is 1.
Therefore, GCD of numbers 207, 145, 777, 197 is 1
Given Input Data is 207, 145, 777, 197
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 207 is 3 x 3 x 23
Prime Factorization of 145 is 5 x 29
Prime Factorization of 777 is 3 x 7 x 37
Prime Factorization of 197 is 197
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(207, 145) = 30015
GCD(207, 145) = ( 207 x 145 ) / 30015
GCD(207, 145) = 30015 / 30015
GCD(207, 145) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 777
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 777) = 777
GCD(1, 777) = ( 1 x 777 ) / 777
GCD(1, 777) = 777 / 777
GCD(1, 777) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 197
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
GCD(1, 197) = 197 / 197
GCD(1, 197) = 1
GCD of 207, 145, 777, 197 is 1
