Lets's calculate LCM of 390,674
2 | 390, 674 |
195, 337 |
∴ So the LCM of the given numbers is 2 x 195 x 337 = 131430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/131430
Therefore, the GCF of Fractions 266/390,381/674 is 1/131430
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 390,674 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,674) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(390,674) x common factors =2 x 1 = 2
LCM(390,674) = ( 390 × 674 ) / 2
LCM(390,674) = 262860 / 2
LCM(390,674) = 131430
