:1,2,3,6,73,146,219,438
Greatest Common Factor
We found the factors 438,438 . The biggest common factor number is the GCF number.
So the greatest common factor 438,438 is 438.
Lets's calculate LCM of 338,273
13 | 338, 273 |
26, 21 |
∴ So the LCM of the given numbers is 13 x 26 x 21 = 7098
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 438/7098
Therefore, the GCF of Fractions 438/338,438/273 is 438/7098
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 338,273 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(338,273) = 13
common factors(in case of two or more numbers have common factors) = 1
GCF(338,273) x common factors =13 x 1 = 13
LCM(338,273) = ( 338 × 273 ) / 13
LCM(338,273) = 92274 / 13
LCM(338,273) = 7098
