So the greatest common factor 8,24,91,648 is 1.
Lets's calculate LCM of 81,81,902,191
3 | 81, 81, 902, 191 |
3 | 27, 27, 902, 191 |
3 | 9, 9, 902, 191 |
3 | 3, 3, 902, 191 |
1, 1, 902, 191 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 1 x 1 x 902 x 191 = 13954842
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13954842
Therefore, the GCF of Fractions 8/81,24/81,91/902,648/191 is 1/13954842
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 81,81,902,191 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,81,902,191) = 1
common factors(in case of two or more numbers have common factors) = 81
GCF(81,81,902,191) x common factors =1 x 81 = 81
LCM(81,81,902,191) = ( 81 × 81 × 902 × 191 ) / 81
LCM(81,81,902,191) = 1130342202 / 81
LCM(81,81,902,191) = 13954842
