Now, list down the factors of 842
:1,2,421,842
Now, list down the factors of 745
:1,5,149,745
Greatest Common Factor
We found the factors 842,745 . The biggest common factor number is the GCF number.
So the greatest common factor 842,745 is 1.
Lets's calculate LCM of 10,209
Given numbers has no common factors except 1. So, there LCM is their product i.e 2090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2090
Therefore, the GCF of Fractions 842/10,745/209 is 1/2090
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 10,209 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(10,209) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(10,209) x common factors =1 x 1 = 1
LCM(10,209) = ( 10 × 209 ) / 1
LCM(10,209) = 2090 / 1
LCM(10,209) = 2090
