Greatest Common Divisior
We found the divisors of 293, 840, 657, 755 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 293, 840, 657, 755 is 1.
Therefore, GCD of numbers 293, 840, 657, 755 is 1
Given Input Data is 293, 840, 657, 755
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 293 is 293
Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7
Prime Factorization of 657 is 3 x 3 x 73
Prime Factorization of 755 is 5 x 151
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(293, 840) = 246120
GCD(293, 840) = ( 293 x 840 ) / 246120
GCD(293, 840) = 246120 / 246120
GCD(293, 840) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 657
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
GCD(1, 657) = 657 / 657
GCD(1, 657) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 755
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
GCD(1, 755) = 755 / 755
GCD(1, 755) = 1
GCD of 293, 840, 657, 755 is 1
