So the greatest common factor 180,1791 is 9.
Lets's calculate LCM of 878,428
2 | 878, 428 |
439, 214 |
∴ So the LCM of the given numbers is 2 x 439 x 214 = 187892
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/187892
Therefore, the GCF of Fractions 180/878,1791/428 is 9/187892
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 878,428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(878,428) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(878,428) x common factors =2 x 1 = 2
LCM(878,428) = ( 878 × 428 ) / 2
LCM(878,428) = 375784 / 2
LCM(878,428) = 187892
