Greatest Common Factor
We found the factors 68,528,490 . The biggest common factor number is the GCF number.
So the greatest common factor 68,528,490 is 2.
Lets's calculate LCM of 40,68,89
2 | 40, 68, 89 |
2 | 20, 34, 89 |
10, 17, 89 |
∴ So the LCM of the given numbers is 2 x 2 x 10 x 17 x 89 = 60520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/60520
Therefore, the GCF of Fractions 68/40,528/68,490/89 is 2/60520
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 40,68,89 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,68,89) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(40,68,89) x common factors =1 x 4 = 4
LCM(40,68,89) = ( 40 × 68 × 89 ) / 4
LCM(40,68,89) = 242080 / 4
LCM(40,68,89) = 60520
