Greatest Common Factor
We found the factors 721,547 . The biggest common factor number is the GCF number.
So the greatest common factor 721,547 is 1.
Lets's calculate LCM of 310,896
2 | 310, 896 |
155, 448 |
∴ So the LCM of the given numbers is 2 x 155 x 448 = 138880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/138880
Therefore, the GCF of Fractions 721/310,547/896 is 1/138880
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 310,896 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(310,896) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(310,896) x common factors =2 x 1 = 2
LCM(310,896) = ( 310 × 896 ) / 2
LCM(310,896) = 277760 / 2
LCM(310,896) = 138880
