:1,3,5,15,43,129,215,645
Greatest Common Factor
We found the factors 363,645 . The biggest common factor number is the GCF number.
So the greatest common factor 363,645 is 3.
Lets's calculate LCM of 687,930
3 | 687, 930 |
229, 310 |
∴ So the LCM of the given numbers is 3 x 229 x 310 = 212970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/212970
Therefore, the GCF of Fractions 363/687,645/930 is 3/212970
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 687,930 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(687,930) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(687,930) x common factors =3 x 1 = 3
LCM(687,930) = ( 687 × 930 ) / 3
LCM(687,930) = 638910 / 3
LCM(687,930) = 212970
