Greatest Common Factor
We found the factors 85,90,908 . The biggest common factor number is the GCF number.
So the greatest common factor 85,90,908 is 1.
Lets's calculate LCM of 36,45,618
2 | 36, 45, 618 |
3 | 18, 45, 309 |
3 | 6, 15, 103 |
2, 5, 103 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 2 x 5 x 103 = 18540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18540
Therefore, the GCF of Fractions 85/36,90/45,908/618 is 1/18540
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 36,45,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(36,45,618) = 3
common factors(in case of two or more numbers have common factors) = 18
GCF(36,45,618) x common factors =3 x 18 = 54
LCM(36,45,618) = ( 36 × 45 × 618 ) / 54
LCM(36,45,618) = 1001160 / 54
LCM(36,45,618) = 18540
