Lets's calculate LCM of 46,44,447
2 | 46, 44, 447 |
23, 22, 447 |
∴ So the LCM of the given numbers is 2 x 23 x 22 x 447 = 452364
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/452364
Therefore, the GCF of Fractions 390/46,844/44,902/447 is 2/452364
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 46,44,447 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(46,44,447) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(46,44,447) x common factors =1 x 2 = 2
LCM(46,44,447) = ( 46 × 44 × 447 ) / 2
LCM(46,44,447) = 904728 / 2
LCM(46,44,447) = 452364
