Lets's calculate LCM of 81,702
3 | 81, 702 |
3 | 27, 234 |
3 | 9, 78 |
3, 26 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 26 = 2106
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2106
Therefore, the GCF of Fractions 487/81,388/702 is 1/2106
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 81,702 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,702) = 27
common factors(in case of two or more numbers have common factors) = 1
GCF(81,702) x common factors =27 x 1 = 27
LCM(81,702) = ( 81 × 702 ) / 27
LCM(81,702) = 56862 / 27
LCM(81,702) = 2106
