Greatest Common Divisior
We found the divisors of 100, 929, 780, 646 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 100, 929, 780, 646 is 1.
Therefore, GCD of numbers 100, 929, 780, 646 is 1
Given Input Data is 100, 929, 780, 646
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 100 is 2 x 2 x 5 x 5
Prime Factorization of 929 is 929
Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13
Prime Factorization of 646 is 2 x 17 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(100, 929) = 92900
GCD(100, 929) = ( 100 x 929 ) / 92900
GCD(100, 929) = 92900 / 92900
GCD(100, 929) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 780
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
GCD(1, 780) = 780 / 780
GCD(1, 780) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 646
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
GCD(1, 646) = 646 / 646
GCD(1, 646) = 1
GCD of 100, 929, 780, 646 is 1
