So the greatest common factor 121,396 is 11.
Lets's calculate LCM of 38,930
2 | 38, 930 |
19, 465 |
∴ So the LCM of the given numbers is 2 x 19 x 465 = 17670
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/17670
Therefore, the GCF of Fractions 121/38,396/930 is 11/17670
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 38,930 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,930) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(38,930) x common factors =2 x 1 = 2
LCM(38,930) = ( 38 × 930 ) / 2
LCM(38,930) = 35340 / 2
LCM(38,930) = 17670
