Lets's calculate LCM of 642,825,840
2 | 642, 825, 840 |
3 | 321, 825, 420 |
5 | 107, 275, 140 |
107, 55, 28 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 107 x 55 x 28 = 4943400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4943400
Therefore, the GCF of Fractions 519/642,210/825,811/840 is 1/4943400
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 642,825,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,825,840) = 3
common factors(in case of two or more numbers have common factors) = 30
GCF(642,825,840) x common factors =3 x 30 = 90
LCM(642,825,840) = ( 642 × 825 × 840 ) / 90
LCM(642,825,840) = 444906000 / 90
LCM(642,825,840) = 4943400
