So the greatest common factor 14,72,48 is 2.
Lets's calculate LCM of 68,30,448
2 | 68, 30, 448 |
2 | 34, 15, 224 |
17, 15, 112 |
∴ So the LCM of the given numbers is 2 x 2 x 17 x 15 x 112 = 114240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/114240
Therefore, the GCF of Fractions 14/68,72/30,48/448 is 2/114240
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 68,30,448 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,30,448) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(68,30,448) x common factors =2 x 4 = 8
LCM(68,30,448) = ( 68 × 30 × 448 ) / 8
LCM(68,30,448) = 913920 / 8
LCM(68,30,448) = 114240
