1, 2, 4, 8, 17, 34, 68, 136
Greatest Common Divisior
We found the divisors of 418, 637, 79, 136 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 418, 637, 79, 136 is 1.
Therefore, GCD of numbers 418, 637, 79, 136 is 1
Given Input Data is 418, 637, 79, 136
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 418 is 2 x 11 x 19
Prime Factorization of 637 is 7 x 7 x 13
Prime Factorization of 79 is 79
Prime Factorization of 136 is 2 x 2 x 2 x 17
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(418, 637) = 266266
GCD(418, 637) = ( 418 x 637 ) / 266266
GCD(418, 637) = 266266 / 266266
GCD(418, 637) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 79
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 79) = 79
GCD(1, 79) = ( 1 x 79 ) / 79
GCD(1, 79) = 79 / 79
GCD(1, 79) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 136
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 136) = 136
GCD(1, 136) = ( 1 x 136 ) / 136
GCD(1, 136) = 136 / 136
GCD(1, 136) = 1
GCD of 418, 637, 79, 136 is 1
