Lets's calculate LCM of 948,205,936
2 | 948, 205, 936 |
2 | 474, 205, 468 |
3 | 237, 205, 234 |
79, 205, 78 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 79 x 205 x 78 = 15158520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 19/15158520
Therefore, the GCF of Fractions 19/948,38/205,855/936 is 19/15158520
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 948,205,936 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(948,205,936) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(948,205,936) x common factors =1 x 12 = 12
LCM(948,205,936) = ( 948 × 205 × 936 ) / 12
LCM(948,205,936) = 181902240 / 12
LCM(948,205,936) = 15158520
