Greatest Common Factor
We found the factors 15,45,475 . The biggest common factor number is the GCF number.
So the greatest common factor 15,45,475 is 5.
Lets's calculate LCM of 24,836,399
2 | 24, 836, 399 |
2 | 12, 418, 399 |
3 | 6, 209, 399 |
19 | 2, 209, 133 |
2, 11, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 19 x 2 x 11 x 7 = 35112
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/35112
Therefore, the GCF of Fractions 15/24,45/836,475/399 is 5/35112
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 24,836,399 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,836,399) = 1
common factors(in case of two or more numbers have common factors) = 228
GCF(24,836,399) x common factors =1 x 228 = 228
LCM(24,836,399) = ( 24 × 836 × 399 ) / 228
LCM(24,836,399) = 8005536 / 228
LCM(24,836,399) = 35112
