So the greatest common factor 66,39,243 is 3.
Lets's calculate LCM of 161,489,456
3 | 161, 489, 456 |
161, 163, 152 |
∴ So the LCM of the given numbers is 3 x 161 x 163 x 152 = 11966808
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/11966808
Therefore, the GCF of Fractions 66/161,39/489,243/456 is 3/11966808
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 161,489,456 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(161,489,456) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(161,489,456) x common factors =1 x 3 = 3
LCM(161,489,456) = ( 161 × 489 × 456 ) / 3
LCM(161,489,456) = 35900424 / 3
LCM(161,489,456) = 11966808
