Lets's calculate LCM of 515,622,230
2 | 515, 622, 230 |
5 | 515, 311, 115 |
103, 311, 23 |
∴ So the LCM of the given numbers is 2 x 5 x 103 x 311 x 23 = 7367590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7367590
Therefore, the GCF of Fractions 391/515,868/622,861/230 is 1/7367590
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 515,622,230 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(515,622,230) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(515,622,230) x common factors =1 x 10 = 10
LCM(515,622,230) = ( 515 × 622 × 230 ) / 10
LCM(515,622,230) = 73675900 / 10
LCM(515,622,230) = 7367590
