Lets's calculate LCM of 298,436
2 | 298, 436 |
149, 218 |
∴ So the LCM of the given numbers is 2 x 149 x 218 = 64964
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 43/64964
Therefore, the GCF of Fractions 645/298,3311/436 is 43/64964
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 298,436 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(298,436) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(298,436) x common factors =2 x 1 = 2
LCM(298,436) = ( 298 × 436 ) / 2
LCM(298,436) = 129928 / 2
LCM(298,436) = 64964
