Greatest Common Factor
We found the factors 221,388 . The biggest common factor number is the GCF number.
So the greatest common factor 221,388 is 1.
Lets's calculate LCM of 710,618
2 | 710, 618 |
355, 309 |
∴ So the LCM of the given numbers is 2 x 355 x 309 = 219390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/219390
Therefore, the GCF of Fractions 221/710,388/618 is 1/219390
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 710,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(710,618) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(710,618) x common factors =2 x 1 = 2
LCM(710,618) = ( 710 × 618 ) / 2
LCM(710,618) = 438780 / 2
LCM(710,618) = 219390
