1,3,7,21,41,123,287,861
Greatest Common Factor
We found the factors 702,124,861 . The biggest common factor number is the GCF number.
So the greatest common factor 702,124,861 is 1.
Lets's calculate LCM of 60,81,11
3 | 60, 81, 11 |
20, 27, 11 |
∴ So the LCM of the given numbers is 3 x 20 x 27 x 11 = 17820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17820
Therefore, the GCF of Fractions 702/60,124/81,861/11 is 1/17820
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 60,81,11 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,81,11) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(60,81,11) x common factors =1 x 3 = 3
LCM(60,81,11) = ( 60 × 81 × 11 ) / 3
LCM(60,81,11) = 53460 / 3
LCM(60,81,11) = 17820
