:1,3,7,21,47,141,329,987
Greatest Common Factor
We found the factors 102,987 . The biggest common factor number is the GCF number.
So the greatest common factor 102,987 is 3.
Lets's calculate LCM of 975,612
3 | 975, 612 |
325, 204 |
∴ So the LCM of the given numbers is 3 x 325 x 204 = 198900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/198900
Therefore, the GCF of Fractions 102/975,987/612 is 3/198900
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 975,612 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(975,612) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(975,612) x common factors =3 x 1 = 3
LCM(975,612) = ( 975 × 612 ) / 3
LCM(975,612) = 596700 / 3
LCM(975,612) = 198900
