Lets's calculate LCM of 442,364
2 | 442, 364 |
13 | 221, 182 |
17, 14 |
∴ So the LCM of the given numbers is 2 x 13 x 17 x 14 = 6188
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/6188
Therefore, the GCF of Fractions 408/442,7230/364 is 6/6188
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 442,364 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(442,364) = 26
common factors(in case of two or more numbers have common factors) = 1
GCF(442,364) x common factors =26 x 1 = 26
LCM(442,364) = ( 442 × 364 ) / 26
LCM(442,364) = 160888 / 26
LCM(442,364) = 6188
