So the greatest common factor 108,392 is 4.
Lets's calculate LCM of 46,672
2 | 46, 672 |
23, 336 |
∴ So the LCM of the given numbers is 2 x 23 x 336 = 15456
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/15456
Therefore, the GCF of Fractions 108/46,392/672 is 4/15456
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 46,672 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(46,672) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(46,672) x common factors =2 x 1 = 2
LCM(46,672) = ( 46 × 672 ) / 2
LCM(46,672) = 30912 / 2
LCM(46,672) = 15456
