Greatest Common Divisior
We found the divisors of 88, 153, 638, 475 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 88, 153, 638, 475 is 1.
Therefore, GCD of numbers 88, 153, 638, 475 is 1
Given Input Data is 88, 153, 638, 475
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 88 is 2 x 2 x 2 x 11
Prime Factorization of 153 is 3 x 3 x 17
Prime Factorization of 638 is 2 x 11 x 29
Prime Factorization of 475 is 5 x 5 x 19
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(88, 153) = 13464
GCD(88, 153) = ( 88 x 153 ) / 13464
GCD(88, 153) = 13464 / 13464
GCD(88, 153) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 638
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
GCD(1, 638) = 638 / 638
GCD(1, 638) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 475
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
GCD(1, 475) = 475 / 475
GCD(1, 475) = 1
GCD of 88, 153, 638, 475 is 1
