Lets's calculate LCM of 278,132
2 | 278, 132 |
139, 66 |
∴ So the LCM of the given numbers is 2 x 139 x 66 = 18348
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/18348
Therefore, the GCF of Fractions 388/278,208/132 is 4/18348
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 278,132 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(278,132) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(278,132) x common factors =2 x 1 = 2
LCM(278,132) = ( 278 × 132 ) / 2
LCM(278,132) = 36696 / 2
LCM(278,132) = 18348
