Lets's calculate LCM of 240,768,400
2 | 240, 768, 400 |
2 | 120, 384, 200 |
2 | 60, 192, 100 |
2 | 30, 96, 50 |
3 | 15, 48, 25 |
5 | 5, 16, 25 |
1, 16, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 1 x 16 x 5 = 19200
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19200
Therefore, the GCF of Fractions 23/240,868/768,905/400 is 1/19200
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 240,768,400 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(240,768,400) = 16
common factors(in case of two or more numbers have common factors) = 240
GCF(240,768,400) x common factors =16 x 240 = 3840
LCM(240,768,400) = ( 240 × 768 × 400 ) / 3840
LCM(240,768,400) = 73728000 / 3840
LCM(240,768,400) = 19200
