Lets's calculate LCM of 249,834
3 | 249, 834 |
83, 278 |
∴ So the LCM of the given numbers is 3 x 83 x 278 = 69222
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/69222
Therefore, the GCF of Fractions 625/249,648/834 is 1/69222
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 249,834 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(249,834) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(249,834) x common factors =3 x 1 = 3
LCM(249,834) = ( 249 × 834 ) / 3
LCM(249,834) = 207666 / 3
LCM(249,834) = 69222
