So the greatest common factor 684,610 is 2.
Lets's calculate LCM of 660,615
3 | 660, 615 |
5 | 220, 205 |
44, 41 |
∴ So the LCM of the given numbers is 3 x 5 x 44 x 41 = 27060
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/27060
Therefore, the GCF of Fractions 684/660,610/615 is 2/27060
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 660,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(660,615) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(660,615) x common factors =15 x 1 = 15
LCM(660,615) = ( 660 × 615 ) / 15
LCM(660,615) = 405900 / 15
LCM(660,615) = 27060
