Greatest Common Divisior
We found the divisors of 749, 621, 43 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 749, 621, 43 is 1.
Therefore, GCD of numbers 749, 621, 43 is 1
Given Input Data is 749, 621, 43
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 749 is 7 x 107
Prime Factorization of 621 is 3 x 3 x 3 x 23
Prime Factorization of 43 is 43
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(749, 621) = 465129
GCD(749, 621) = ( 749 x 621 ) / 465129
GCD(749, 621) = 465129 / 465129
GCD(749, 621) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 43
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 43) = 43
GCD(1, 43) = ( 1 x 43 ) / 43
GCD(1, 43) = 43 / 43
GCD(1, 43) = 1
GCD of 749, 621, 43 is 1
