Greatest Common Divisior
We found the divisors of 730, 124, 86, 855 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 730, 124, 86, 855 is 1.
Therefore, GCD of numbers 730, 124, 86, 855 is 1
Given Input Data is 730, 124, 86, 855
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 730 is 2 x 5 x 73
Prime Factorization of 124 is 2 x 2 x 31
Prime Factorization of 86 is 2 x 43
Prime Factorization of 855 is 3 x 3 x 5 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(730, 124) = 45260
GCD(730, 124) = ( 730 x 124 ) / 45260
GCD(730, 124) = 90520 / 45260
GCD(730, 124) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 86
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 86) = 86
GCD(2, 86) = ( 2 x 86 ) / 86
GCD(2, 86) = 172 / 86
GCD(2, 86) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 855
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 855) = 1710
GCD(2, 855) = ( 2 x 855 ) / 1710
GCD(2, 855) = 1710 / 1710
GCD(2, 855) = 1
GCD of 730, 124, 86, 855 is 1
