Now, list down the factors of 445
:1,5,89,445
Now, list down the factors of 764
:1,2,4,191,382,764
Greatest Common Factor
We found the factors 445,764 . The biggest common factor number is the GCF number.
So the greatest common factor 445,764 is 1.
Lets's calculate LCM of 305,621
Given numbers has no common factors except 1. So, there LCM is their product i.e 189405
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/189405
Therefore, the GCF of Fractions 445/305,764/621 is 1/189405
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 305,621 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(305,621) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(305,621) x common factors =1 x 1 = 1
LCM(305,621) = ( 305 × 621 ) / 1
LCM(305,621) = 189405 / 1
LCM(305,621) = 189405
