Lets's calculate GCF of 170,985
5 | 170, 985 |
34, 197 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 170
:1,2,5,10,17,34,85,170
Now, list down the factors of 985
:1,5,197,985
Greatest Common Factor
We found the factors 170,985 . The biggest common factor number is the GCF number.
So the greatest common factor 170,985 is 5.
Lets's calculate LCM of 808,417
Given numbers has no common factors except 1. So, there LCM is their product i.e 336936
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/336936
Therefore, the GCF of Fractions 170/808,985/417 is 5/336936
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 808,417 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(808,417) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(808,417) x common factors =1 x 1 = 1
LCM(808,417) = ( 808 × 417 ) / 1
LCM(808,417) = 336936 / 1
LCM(808,417) = 336936
