So the greatest common factor 48,47,847 is 1.
Lets's calculate LCM of 420,875,531
3 | 420, 875, 531 |
5 | 140, 875, 177 |
7 | 28, 175, 177 |
4, 25, 177 |
∴ So the LCM of the given numbers is 3 x 5 x 7 x 4 x 25 x 177 = 1858500
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1858500
Therefore, the GCF of Fractions 48/420,47/875,847/531 is 1/1858500
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 420,875,531 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,875,531) = 1
common factors(in case of two or more numbers have common factors) = 105
GCF(420,875,531) x common factors =1 x 105 = 105
LCM(420,875,531) = ( 420 × 875 × 531 ) / 105
LCM(420,875,531) = 195142500 / 105
LCM(420,875,531) = 1858500
