1,2,4,8,53,106,212,424
Greatest Common Factor
We found the factors 455,424 . The biggest common factor number is the GCF number.
So the greatest common factor 455,424 is 1.
Lets's calculate LCM of 1507,4209
Given numbers has no common factors except 1. So, there LCM is their product i.e 6342963
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6342963
Therefore, the GCF of Fractions 455/1507,424/4209 is 1/6342963
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 1507,4209 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1507,4209) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(1507,4209) x common factors =1 x 1 = 1
LCM(1507,4209) = ( 1507 × 4209 ) / 1
LCM(1507,4209) = 6342963 / 1
LCM(1507,4209) = 6342963
Here are some samples of GCF of Fractions calculations.
