1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
Greatest Common Divisior
We found the divisors of 915, 250, 65, 798 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 915, 250, 65, 798 is 1.
Therefore, GCD of numbers 915, 250, 65, 798 is 1
Given Input Data is 915, 250, 65, 798
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 915 is 3 x 5 x 61
Prime Factorization of 250 is 2 x 5 x 5 x 5
Prime Factorization of 65 is 5 x 13
Prime Factorization of 798 is 2 x 3 x 7 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(915, 250) = 45750
GCD(915, 250) = ( 915 x 250 ) / 45750
GCD(915, 250) = 228750 / 45750
GCD(915, 250) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 65
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 65) = 65
GCD(5, 65) = ( 5 x 65 ) / 65
GCD(5, 65) = 325 / 65
GCD(5, 65) = 5
Step3:
Here we consider the GCD from the above i.e. 5 as first number and the next as 798
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 798) = 3990
GCD(5, 798) = ( 5 x 798 ) / 3990
GCD(5, 798) = 3990 / 3990
GCD(5, 798) = 1
GCD of 915, 250, 65, 798 is 1
