Greatest Common Factor
We found the factors 651,990 . The biggest common factor number is the GCF number.
So the greatest common factor 651,990 is 3.
Lets's calculate LCM of 807,693
3 | 807, 693 |
269, 231 |
∴ So the LCM of the given numbers is 3 x 269 x 231 = 186417
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/186417
Therefore, the GCF of Fractions 651/807,990/693 is 3/186417
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 807,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(807,693) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(807,693) x common factors =3 x 1 = 3
LCM(807,693) = ( 807 × 693 ) / 3
LCM(807,693) = 559251 / 3
LCM(807,693) = 186417
