The factors of 803 are 1, 11, 73, 803
The HCF of 165,803 is 11.
Lets's calculate GCF of 165,803
11 | 165, 803 |
15, 73 |
∴ So the GCF of the given numbers is 11 = 11
Now, list down the factors of 165
:1,3,5,11,15,33,55,165
Now, list down the factors of 803
:1,11,73,803
Greatest Common Factor
We found the factors 165,803 . The biggest common factor number is the GCF number.
So the greatest common factor 165,803 is 11.
Lets's calculate LCM of 89,805
Given numbers has no common factors except 1. So, there LCM is their product i.e 71645
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/71645
Therefore, the GCF of Fractions 165/89,803/805 is 11/71645
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 89,805 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,805) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,805) x common factors =1 x 1 = 1
LCM(89,805) = ( 89 × 805 ) / 1
LCM(89,805) = 71645 / 1
LCM(89,805) = 71645
