Lets's calculate LCM of 715,2959
11 | 715, 2959 |
65, 269 |
∴ So the LCM of the given numbers is 11 x 65 x 269 = 192335
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/192335
Therefore, the GCF of Fractions 1128/715,6890/2959 is 2/192335
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 715,2959 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(715,2959) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(715,2959) x common factors =11 x 1 = 11
LCM(715,2959) = ( 715 × 2959 ) / 11
LCM(715,2959) = 2115685 / 11
LCM(715,2959) = 192335
