Lets's calculate LCM of 278,405
Given numbers has no common factors except 1. So, there LCM is their product i.e 112590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/112590
Therefore, the GCF of Fractions 1902/278,7874/405 is 2/112590
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 278,405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(278,405) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(278,405) x common factors =1 x 1 = 1
LCM(278,405) = ( 278 × 405 ) / 1
LCM(278,405) = 112590 / 1
LCM(278,405) = 112590
Here are some samples of GCF of Fractions calculations.
