Lets's calculate GCF of 153,823
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 153
:1,3,9,17,51,153
Now, list down the factors of 823
:1,823
Greatest Common Factor
We found the factors 153,823 . The biggest common factor number is the GCF number.
So the greatest common factor 153,823 is 1.
Lets's calculate LCM of 247,578
Given numbers has no common factors except 1. So, there LCM is their product i.e 142766
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/142766
Therefore, the GCF of Fractions 153/247,823/578 is 1/142766
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 247,578 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(247,578) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(247,578) x common factors =1 x 1 = 1
LCM(247,578) = ( 247 × 578 ) / 1
LCM(247,578) = 142766 / 1
LCM(247,578) = 142766
