1,47
Factors of 258
List of positive integer factors of 258 that divides 258 without a remainder.
1,2,3,6,43,86,129,258
Greatest Common Factor
We found the factors 40,11,47,258 . The biggest common factor number is the GCF number.
So the greatest common factor 40,11,47,258 is 1.
Lets's calculate LCM of 78,74,29,88
2 | 78, 74, 29, 88 |
39, 37, 29, 44 |
∴ So the LCM of the given numbers is 2 x 39 x 37 x 29 x 44 = 3682536
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3682536
Therefore, the GCF of Fractions 40/78,11/74,47/29,258/88 is 1/3682536
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 78,74,29,88 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,74,29,88) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(78,74,29,88) x common factors =1 x 4 = 4
LCM(78,74,29,88) = ( 78 × 74 × 29 × 88 ) / 4
LCM(78,74,29,88) = 14730144 / 4
LCM(78,74,29,88) = 3682536
