So the greatest common factor 90,94,857 is 1.
Lets's calculate LCM of 255,836,838
2 | 255, 836, 838 |
255, 418, 419 |
∴ So the LCM of the given numbers is 2 x 255 x 418 x 419 = 89322420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/89322420
Therefore, the GCF of Fractions 90/255,94/836,857/838 is 1/89322420
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 255,836,838 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(255,836,838) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(255,836,838) x common factors =1 x 2 = 2
LCM(255,836,838) = ( 255 × 836 × 838 ) / 2
LCM(255,836,838) = 178644840 / 2
LCM(255,836,838) = 89322420
