Lets's calculate GCF of 921,957
3 | 921, 957 |
307, 319 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 921
:1,3,307,921
Now, list down the factors of 957
:1,3,11,29,33,87,319,957
Greatest Common Factor
We found the factors 921,957 . The biggest common factor number is the GCF number.
So the greatest common factor 921,957 is 3.
Lets's calculate LCM of 653,902
Given numbers has no common factors except 1. So, there LCM is their product i.e 589006
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/589006
Therefore, the GCF of Fractions 921/653,957/902 is 3/589006
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 653,902 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(653,902) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(653,902) x common factors =1 x 1 = 1
LCM(653,902) = ( 653 × 902 ) / 1
LCM(653,902) = 589006 / 1
LCM(653,902) = 589006
