Lets's calculate LCM of 939,213
3 | 939, 213 |
313, 71 |
∴ So the LCM of the given numbers is 3 x 313 x 71 = 66669
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/66669
Therefore, the GCF of Fractions 632/939,640/213 is 8/66669
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 939,213 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(939,213) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(939,213) x common factors =3 x 1 = 3
LCM(939,213) = ( 939 × 213 ) / 3
LCM(939,213) = 200007 / 3
LCM(939,213) = 66669
