So the greatest common factor 54,58,470 is 2.
Lets's calculate LCM of 820,234,144
2 | 820, 234, 144 |
2 | 410, 117, 72 |
3 | 205, 117, 36 |
3 | 205, 39, 12 |
205, 13, 4 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 205 x 13 x 4 = 383760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/383760
Therefore, the GCF of Fractions 54/820,58/234,470/144 is 2/383760
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 820,234,144 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(820,234,144) = 2
common factors(in case of two or more numbers have common factors) = 36
GCF(820,234,144) x common factors =2 x 36 = 72
LCM(820,234,144) = ( 820 × 234 × 144 ) / 72
LCM(820,234,144) = 27630720 / 72
LCM(820,234,144) = 383760
