Lets's calculate GCF of 213,828
3 | 213, 828 |
71, 276 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 213
:1,3,71,213
Now, list down the factors of 828
:1,2,3,4,6,9,12,18,23,36,46,69,92,138,207,276,414,828
Greatest Common Factor
We found the factors 213,828 . The biggest common factor number is the GCF number.
So the greatest common factor 213,828 is 3.
Lets's calculate LCM of 905,504
Given numbers has no common factors except 1. So, there LCM is their product i.e 456120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/456120
Therefore, the GCF of Fractions 213/905,828/504 is 3/456120
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 905,504 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(905,504) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(905,504) x common factors =1 x 1 = 1
LCM(905,504) = ( 905 × 504 ) / 1
LCM(905,504) = 456120 / 1
LCM(905,504) = 456120
