Lets's calculate LCM of 64,388
2 | 64, 388 |
2 | 32, 194 |
16, 97 |
∴ So the LCM of the given numbers is 2 x 2 x 16 x 97 = 6208
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/6208
Therefore, the GCF of Fractions 7389/64,4392/388 is 9/6208
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 64,388 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,388) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(64,388) x common factors =4 x 1 = 4
LCM(64,388) = ( 64 × 388 ) / 4
LCM(64,388) = 24832 / 4
LCM(64,388) = 6208
