Lets's calculate LCM of 981,545
109 | 981, 545 |
9, 5 |
∴ So the LCM of the given numbers is 109 x 9 x 5 = 4905
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4905
Therefore, the GCF of Fractions 392/981,971/545 is 1/4905
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 981,545 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(981,545) = 109
common factors(in case of two or more numbers have common factors) = 1
GCF(981,545) x common factors =109 x 1 = 109
LCM(981,545) = ( 981 × 545 ) / 109
LCM(981,545) = 534645 / 109
LCM(981,545) = 4905
