So the greatest common factor 91,87,855 is 1.
Lets's calculate LCM of 896,308,247
2 | 896, 308, 247 |
2 | 448, 154, 247 |
7 | 224, 77, 247 |
32, 11, 247 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 32 x 11 x 247 = 2434432
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2434432
Therefore, the GCF of Fractions 91/896,87/308,855/247 is 1/2434432
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 896,308,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(896,308,247) = 1
common factors(in case of two or more numbers have common factors) = 28
GCF(896,308,247) x common factors =1 x 28 = 28
LCM(896,308,247) = ( 896 × 308 × 247 ) / 28
LCM(896,308,247) = 68164096 / 28
LCM(896,308,247) = 2434432
