Lets's calculate LCM of 239,478
239 | 239, 478 |
1, 2 |
∴ So the LCM of the given numbers is 239 x 1 x 2 = 478
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/478
Therefore, the GCF of Fractions 278/239,860/478 is 2/478
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 239,478 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(239,478) = 239
common factors(in case of two or more numbers have common factors) = 1
GCF(239,478) x common factors =239 x 1 = 239
LCM(239,478) = ( 239 × 478 ) / 239
LCM(239,478) = 114242 / 239
LCM(239,478) = 478
