Lets's calculate GCF of 742,843
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 742
:1,2,7,14,53,106,371,742
Now, list down the factors of 843
:1,3,281,843
Greatest Common Factor
We found the factors 742,843 . The biggest common factor number is the GCF number.
So the greatest common factor 742,843 is 1.
Lets's calculate LCM of 33,155
Given numbers has no common factors except 1. So, there LCM is their product i.e 5115
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5115
Therefore, the GCF of Fractions 742/33,843/155 is 1/5115
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 33,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(33,155) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(33,155) x common factors =1 x 1 = 1
LCM(33,155) = ( 33 × 155 ) / 1
LCM(33,155) = 5115 / 1
LCM(33,155) = 5115
