Lets's calculate LCM of 249,838
Given numbers has no common factors except 1. So, there LCM is their product i.e 208662
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 31/208662
Therefore, the GCF of Fractions 7471/249,7719/838 is 31/208662
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 249,838 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(249,838) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(249,838) x common factors =1 x 1 = 1
LCM(249,838) = ( 249 × 838 ) / 1
LCM(249,838) = 208662 / 1
LCM(249,838) = 208662
Here are some samples of GCF of Fractions calculations.
