:1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 135,830 . The biggest common factor number is the GCF number.
So the greatest common factor 135,830 is 5.
Lets's calculate LCM of 687,312
3 | 687, 312 |
229, 104 |
∴ So the LCM of the given numbers is 3 x 229 x 104 = 71448
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/71448
Therefore, the GCF of Fractions 135/687,830/312 is 5/71448
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 687,312 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(687,312) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(687,312) x common factors =3 x 1 = 3
LCM(687,312) = ( 687 × 312 ) / 3
LCM(687,312) = 214344 / 3
LCM(687,312) = 71448
