The HCF of 171,817 is 19.
Lets's calculate GCF of 171,817
| 19 | 171, 817 |
| 9, 43 |
∴ So the GCF of the given numbers is 19 = 19
Now, list down the factors of 171
:1,3,9,19,57,171
Now, list down the factors of 817
:1,19,43,817
Greatest Common Factor
We found the factors 171,817 . The biggest common factor number is the GCF number.
So the greatest common factor 171,817 is 19.
Lets's calculate LCM of 39,4258
Given numbers has no common factors except 1. So, there LCM is their product i.e 166062
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 19/166062
Therefore, the GCF of Fractions 171/39,817/4258 is 19/166062
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 39,4258 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,4258) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,4258) x common factors =1 x 1 = 1
LCM(39,4258) = ( 39 × 4258 ) / 1
LCM(39,4258) = 166062 / 1
LCM(39,4258) = 166062
