Lets's calculate LCM of 648,350
2 | 648, 350 |
324, 175 |
∴ So the LCM of the given numbers is 2 x 324 x 175 = 113400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/113400
Therefore, the GCF of Fractions 392/648,1687/350 is 7/113400
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 648,350 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(648,350) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(648,350) x common factors =2 x 1 = 2
LCM(648,350) = ( 648 × 350 ) / 2
LCM(648,350) = 226800 / 2
LCM(648,350) = 113400
