Lets's calculate LCM of 278,509
Given numbers has no common factors except 1. So, there LCM is their product i.e 141502
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/141502
Therefore, the GCF of Fractions 938/278,8722/509 is 14/141502
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 278,509 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(278,509) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(278,509) x common factors =1 x 1 = 1
LCM(278,509) = ( 278 × 509 ) / 1
LCM(278,509) = 141502 / 1
LCM(278,509) = 141502
Here are some samples of GCF of Fractions calculations.
