So the greatest common factor 957,870 is 87.
Lets's calculate LCM of 258,804
2 | 258, 804 |
3 | 129, 402 |
43, 134 |
∴ So the LCM of the given numbers is 2 x 3 x 43 x 134 = 34572
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 87/34572
Therefore, the GCF of Fractions 957/258,870/804 is 87/34572
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 258,804 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(258,804) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(258,804) x common factors =6 x 1 = 6
LCM(258,804) = ( 258 × 804 ) / 6
LCM(258,804) = 207432 / 6
LCM(258,804) = 34572
