1, 937
Greatest Common Divisior
We found the divisors of 640, 780, 937 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 640, 780, 937 is 1.
Therefore, GCD of numbers 640, 780, 937 is 1
Given Input Data is 640, 780, 937
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13
Prime Factorization of 937 is 937
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(640, 780) = 24960
GCD(640, 780) = ( 640 x 780 ) / 24960
GCD(640, 780) = 499200 / 24960
GCD(640, 780) = 20
Step2:
Here we consider the GCD from the above i.e. 20 as first number and the next as 937
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(20, 937) = 18740
GCD(20, 937) = ( 20 x 937 ) / 18740
GCD(20, 937) = 18740 / 18740
GCD(20, 937) = 1
GCD of 640, 780, 937 is 1
