:1,5,61,305
Now, list down the factors of 286
:1,2,11,13,22,26,143,286
Greatest Common Factor
We found the factors 305,286 . The biggest common factor number is the GCF number.
So the greatest common factor 305,286 is 1.
Lets's calculate LCM of 610,349
Given numbers has no common factors except 1. So, there LCM is their product i.e 212890
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/212890
Therefore, the GCF of Fractions 305/610,286/349 is 1/212890
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 610,349 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(610,349) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(610,349) x common factors =1 x 1 = 1
LCM(610,349) = ( 610 × 349 ) / 1
LCM(610,349) = 212890 / 1
LCM(610,349) = 212890
