:1,5,29,145
Now, list down the factors of 809
:1,809
Greatest Common Factor
We found the factors 145,809 . The biggest common factor number is the GCF number.
So the greatest common factor 145,809 is 1.
Lets's calculate LCM of 19,7145
Given numbers has no common factors except 1. So, there LCM is their product i.e 135755
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/135755
Therefore, the GCF of Fractions 145/19,809/7145 is 1/135755
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 19,7145 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,7145) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,7145) x common factors =1 x 1 = 1
LCM(19,7145) = ( 19 × 7145 ) / 1
LCM(19,7145) = 135755 / 1
LCM(19,7145) = 135755
