Greatest Common Factor
We found the factors 123,4308 . The biggest common factor number is the GCF number.
So the greatest common factor 123,4308 is 3.
Lets's calculate LCM of 85,690
5 | 85, 690 |
17, 138 |
∴ So the LCM of the given numbers is 5 x 17 x 138 = 11730
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/11730
Therefore, the GCF of Fractions 123/85,4308/690 is 3/11730
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 85,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,690) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(85,690) x common factors =5 x 1 = 5
LCM(85,690) = ( 85 × 690 ) / 5
LCM(85,690) = 58650 / 5
LCM(85,690) = 11730
