Lets's calculate LCM of 902,238,867
2 | 902, 238, 867 |
17 | 451, 119, 867 |
451, 7, 51 |
∴ So the LCM of the given numbers is 2 x 17 x 451 x 7 x 51 = 5474238
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/5474238
Therefore, the GCF of Fractions 70/902,770/238,231/867 is 7/5474238
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 902,238,867 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(902,238,867) = 1
common factors(in case of two or more numbers have common factors) = 34
GCF(902,238,867) x common factors =1 x 34 = 34
LCM(902,238,867) = ( 902 × 238 × 867 ) / 34
LCM(902,238,867) = 186124092 / 34
LCM(902,238,867) = 5474238
