Greatest Common Factor
We found the factors 10,208,118 . The biggest common factor number is the GCF number.
So the greatest common factor 10,208,118 is 2.
Lets's calculate LCM of 87,48,261
3 | 87, 48, 261 |
29 | 29, 16, 87 |
1, 16, 3 |
∴ So the LCM of the given numbers is 3 x 29 x 1 x 16 x 3 = 4176
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/4176
Therefore, the GCF of Fractions 10/87,208/48,118/261 is 2/4176
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 87,48,261 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,48,261) = 3
common factors(in case of two or more numbers have common factors) = 87
GCF(87,48,261) x common factors =3 x 87 = 261
LCM(87,48,261) = ( 87 × 48 × 261 ) / 261
LCM(87,48,261) = 1089936 / 261
LCM(87,48,261) = 4176
