Lets's calculate LCM of 260,2246
2 | 260, 2246 |
130, 1123 |
∴ So the LCM of the given numbers is 2 x 130 x 1123 = 291980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/291980
Therefore, the GCF of Fractions 2720/260,1686/2246 is 2/291980
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 260,2246 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(260,2246) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(260,2246) x common factors =2 x 1 = 2
LCM(260,2246) = ( 260 × 2246 ) / 2
LCM(260,2246) = 583960 / 2
LCM(260,2246) = 291980
