Lets's calculate LCM of 666,111
3 | 666, 111 |
37 | 222, 37 |
6, 1 |
∴ So the LCM of the given numbers is 3 x 37 x 6 x 1 = 666
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/666
Therefore, the GCF of Fractions 342/666,129/111 is 3/666
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 666,111 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(666,111) = 111
common factors(in case of two or more numbers have common factors) = 1
GCF(666,111) x common factors =111 x 1 = 111
LCM(666,111) = ( 666 × 111 ) / 111
LCM(666,111) = 73926 / 111
LCM(666,111) = 666
