Greatest Common Divisior
We found the divisors of 640, 743, 878, 109 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 640, 743, 878, 109 is 1.
Therefore, GCD of numbers 640, 743, 878, 109 is 1
Given Input Data is 640, 743, 878, 109
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 743 is 743
Prime Factorization of 878 is 2 x 439
Prime Factorization of 109 is 109
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, 743) = 475520
GCD(640, 743) = ( 640 x 743 ) / 475520
GCD(640, 743) = 475520 / 475520
GCD(640, 743) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 878
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
GCD(1, 878) = 878 / 878
GCD(1, 878) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 109
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
GCD(1, 109) = 109 / 109
GCD(1, 109) = 1
GCD of 640, 743, 878, 109 is 1
