Lets's calculate GCF of 343,686
7 | 343, 686 |
7 | 49, 98 |
7 | 7, 14 |
1, 2 |
∴ So the GCF of the given numbers is 7 x 7 x 7 = 343
Now, list down the factors of 343
:1,7,49,343
Now, list down the factors of 686
:1,2,7,14,49,98,343,686
Greatest Common Factor
We found the factors 343,686 . The biggest common factor number is the GCF number.
So the greatest common factor 343,686 is 343.
Lets's calculate LCM of 345,508
Given numbers has no common factors except 1. So, there LCM is their product i.e 175260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 343/175260
Therefore, the GCF of Fractions 343/345,686/508 is 343/175260
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 345,508 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(345,508) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(345,508) x common factors =1 x 1 = 1
LCM(345,508) = ( 345 × 508 ) / 1
LCM(345,508) = 175260 / 1
LCM(345,508) = 175260
