Lets's calculate LCM of 278,253,286
2 | 278, 253, 286 |
11 | 139, 253, 143 |
139, 23, 13 |
∴ So the LCM of the given numbers is 2 x 11 x 139 x 23 x 13 = 914342
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/914342
Therefore, the GCF of Fractions 90/278,126/253,238/286 is 2/914342
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 278,253,286 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(278,253,286) = 1
common factors(in case of two or more numbers have common factors) = 22
GCF(278,253,286) x common factors =1 x 22 = 22
LCM(278,253,286) = ( 278 × 253 × 286 ) / 22
LCM(278,253,286) = 20115524 / 22
LCM(278,253,286) = 914342
