Greatest Common Factor
We found the factors 89,70,680 . The biggest common factor number is the GCF number.
So the greatest common factor 89,70,680 is 1.
Lets's calculate LCM of 35,81,312
3 | 35, 81, 312 |
35, 27, 104 |
∴ So the LCM of the given numbers is 3 x 35 x 27 x 104 = 294840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/294840
Therefore, the GCF of Fractions 89/35,70/81,680/312 is 1/294840
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 35,81,312 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(35,81,312) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(35,81,312) x common factors =1 x 3 = 3
LCM(35,81,312) = ( 35 × 81 × 312 ) / 3
LCM(35,81,312) = 884520 / 3
LCM(35,81,312) = 294840
