So the greatest common factor 1791,6405 is 3.
Lets's calculate LCM of 306,104
2 | 306, 104 |
153, 52 |
∴ So the LCM of the given numbers is 2 x 153 x 52 = 15912
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/15912
Therefore, the GCF of Fractions 1791/306,6405/104 is 3/15912
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 306,104 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(306,104) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(306,104) x common factors =2 x 1 = 2
LCM(306,104) = ( 306 × 104 ) / 2
LCM(306,104) = 31824 / 2
LCM(306,104) = 15912
