Lets's calculate LCM of 896,396
2 | 896, 396 |
2 | 448, 198 |
224, 99 |
∴ So the LCM of the given numbers is 2 x 2 x 224 x 99 = 88704
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/88704
Therefore, the GCF of Fractions 285/896,5715/396 is 15/88704
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 896,396 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(896,396) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(896,396) x common factors =4 x 1 = 4
LCM(896,396) = ( 896 × 396 ) / 4
LCM(896,396) = 354816 / 4
LCM(896,396) = 88704
