Now, list down the factors of 750
:1,2,3,5,6,10,15,25,30,50,75,125,150,250,375,750
Now, list down the factors of 7890
:1,2,3,5,6,10,15,30,263,526,789,1315,1578,2630,3945,7890
Greatest Common Factor
We found the factors 750,7890 . The biggest common factor number is the GCF number.
So the greatest common factor 750,7890 is 30.
Lets's calculate LCM of 378,551
Given numbers has no common factors except 1. So, there LCM is their product i.e 208278
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/208278
Therefore, the GCF of Fractions 750/378,7890/551 is 30/208278
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 378,551 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(378,551) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(378,551) x common factors =1 x 1 = 1
LCM(378,551) = ( 378 × 551 ) / 1
LCM(378,551) = 208278 / 1
LCM(378,551) = 208278
