Now, list down the factors of 745
:1,5,149,745
Now, list down the factors of 258
:1,2,3,6,43,86,129,258
Greatest Common Factor
We found the factors 74,745,258 . The biggest common factor number is the GCF number.
So the greatest common factor 74,745,258 is 1.
Lets's calculate LCM of 55,40,229
5 | 55, 40, 229 |
11, 8, 229 |
∴ So the LCM of the given numbers is 5 x 11 x 8 x 229 = 100760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/100760
Therefore, the GCF of Fractions 74/55,745/40,258/229 is 1/100760
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 55,40,229 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,40,229) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(55,40,229) x common factors =1 x 5 = 5
LCM(55,40,229) = ( 55 × 40 × 229 ) / 5
LCM(55,40,229) = 503800 / 5
LCM(55,40,229) = 100760
