Greatest Common Factor
We found the factors 16,248,815 . The biggest common factor number is the GCF number.
So the greatest common factor 16,248,815 is 1.
Lets's calculate LCM of 315,648,780
2 | 315, 648, 780 |
2 | 315, 324, 390 |
3 | 315, 162, 195 |
3 | 105, 54, 65 |
5 | 35, 18, 65 |
7, 18, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 5 x 7 x 18 x 13 = 294840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/294840
Therefore, the GCF of Fractions 16/315,248/648,815/780 is 1/294840
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 315,648,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(315,648,780) = 3
common factors(in case of two or more numbers have common factors) = 180
GCF(315,648,780) x common factors =3 x 180 = 540
LCM(315,648,780) = ( 315 × 648 × 780 ) / 540
LCM(315,648,780) = 159213600 / 540
LCM(315,648,780) = 294840
