The HCF of 105,230 is 5.
Lets's calculate GCF of 105,230
5 | 105, 230 |
21, 46 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 105
:1,3,5,7,15,21,35,105
Now, list down the factors of 230
:1,2,5,10,23,46,115,230
Greatest Common Factor
We found the factors 105,230 . The biggest common factor number is the GCF number.
So the greatest common factor 105,230 is 5.
Lets's calculate LCM of 840,221
Given numbers has no common factors except 1. So, there LCM is their product i.e 185640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/185640
Therefore, the GCF of Fractions 105/840,230/221 is 5/185640
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 840,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,221) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(840,221) x common factors =1 x 1 = 1
LCM(840,221) = ( 840 × 221 ) / 1
LCM(840,221) = 185640 / 1
LCM(840,221) = 185640
