The HCF of 212,830 is 2.
Lets's calculate GCF of 212,830
2 | 212, 830 |
106, 415 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 212
:1,2,4,53,106,212
Now, list down the factors of 830
:1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 212,830 . The biggest common factor number is the GCF number.
So the greatest common factor 212,830 is 2.
Lets's calculate LCM of 715,808
Given numbers has no common factors except 1. So, there LCM is their product i.e 577720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/577720
Therefore, the GCF of Fractions 212/715,830/808 is 2/577720
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 715,808 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(715,808) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(715,808) x common factors =1 x 1 = 1
LCM(715,808) = ( 715 × 808 ) / 1
LCM(715,808) = 577720 / 1
LCM(715,808) = 577720
