Factors of 394
List of positive integer factors of 394 that divides 394 without a remainder.
1,2,197,394
Greatest Common Factor
We found the factors 42,22,394 . The biggest common factor number is the GCF number.
So the greatest common factor 42,22,394 is 2.
Lets's calculate LCM of 73,90,88
2 | 73, 90, 88 |
73, 45, 44 |
∴ So the LCM of the given numbers is 2 x 73 x 45 x 44 = 289080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/289080
Therefore, the GCF of Fractions 42/73,22/90,394/88 is 2/289080
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 73,90,88 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(73,90,88) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(73,90,88) x common factors =1 x 2 = 2
LCM(73,90,88) = ( 73 × 90 × 88 ) / 2
LCM(73,90,88) = 578160 / 2
LCM(73,90,88) = 289080
