Lets's calculate LCM of 89,18,690
2 | 89, 18, 690 |
3 | 89, 9, 345 |
89, 3, 115 |
∴ So the LCM of the given numbers is 2 x 3 x 89 x 3 x 115 = 184230
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/184230
Therefore, the GCF of Fractions 87/89,868/18,843/690 is 1/184230
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 89,18,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,18,690) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(89,18,690) x common factors =1 x 6 = 6
LCM(89,18,690) = ( 89 × 18 × 690 ) / 6
LCM(89,18,690) = 1105380 / 6
LCM(89,18,690) = 184230
