Lets's calculate GCF of 89,38
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 680,9115
5 | 680, 9115 |
136, 1823 |
∴ So the LCM of the given numbers is 5 x 136 x 1823 = 1239640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1239640
Therefore, the GCF of Fractions 89/680,38/9115 is 1/1239640
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 680,9115 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(680,9115) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(680,9115) x common factors =5 x 1 = 5
LCM(680,9115) = ( 680 × 9115 ) / 5
LCM(680,9115) = 6198200 / 5
LCM(680,9115) = 1239640
