Lets's calculate LCM of 16,6912
2 | 16, 6912 |
2 | 8, 3456 |
2 | 4, 1728 |
2 | 2, 864 |
1, 432 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 1 x 432 = 6912
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6912
Therefore, the GCF of Fractions 942/16,421/6912 is 1/6912
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 16,6912 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,6912) = 16
common factors(in case of two or more numbers have common factors) = 1
GCF(16,6912) x common factors =16 x 1 = 16
LCM(16,6912) = ( 16 × 6912 ) / 16
LCM(16,6912) = 110592 / 16
LCM(16,6912) = 6912
