:1,719
Now, list down the factors of 170
:1,2,5,10,17,34,85,170
Greatest Common Factor
We found the factors 719,170 . The biggest common factor number is the GCF number.
So the greatest common factor 719,170 is 1.
Lets's calculate LCM of 445,730
5 | 445, 730 |
89, 146 |
∴ So the LCM of the given numbers is 5 x 89 x 146 = 64970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/64970
Therefore, the GCF of Fractions 719/445,170/730 is 1/64970
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 445,730 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(445,730) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(445,730) x common factors =5 x 1 = 5
LCM(445,730) = ( 445 × 730 ) / 5
LCM(445,730) = 324850 / 5
LCM(445,730) = 64970
