Lets's calculate LCM of 285,228
3 | 285, 228 |
19 | 95, 76 |
5, 4 |
∴ So the LCM of the given numbers is 3 x 19 x 5 x 4 = 1140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1140
Therefore, the GCF of Fractions 856/285,551/228 is 1/1140
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 285,228 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(285,228) = 57
common factors(in case of two or more numbers have common factors) = 1
GCF(285,228) x common factors =57 x 1 = 57
LCM(285,228) = ( 285 × 228 ) / 57
LCM(285,228) = 64980 / 57
LCM(285,228) = 1140
