Greatest Common Divisior
We found the divisors of 755, 781, 140, 868 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 755, 781, 140, 868 is 1.
Therefore, GCD of numbers 755, 781, 140, 868 is 1
Given Input Data is 755, 781, 140, 868
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 755 is 5 x 151
Prime Factorization of 781 is 11 x 71
Prime Factorization of 140 is 2 x 2 x 5 x 7
Prime Factorization of 868 is 2 x 2 x 7 x 31
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(755, 781) = 589655
GCD(755, 781) = ( 755 x 781 ) / 589655
GCD(755, 781) = 589655 / 589655
GCD(755, 781) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 140
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
GCD(1, 140) = 140 / 140
GCD(1, 140) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 868
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
GCD(1, 868) = 868 / 868
GCD(1, 868) = 1
GCD of 755, 781, 140, 868 is 1
