So the greatest common factor 11,648,447 is 1.
Lets's calculate LCM of 68,78,789
2 | 68, 78, 789 |
3 | 34, 39, 789 |
34, 13, 263 |
∴ So the LCM of the given numbers is 2 x 3 x 34 x 13 x 263 = 697476
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/697476
Therefore, the GCF of Fractions 11/68,648/78,447/789 is 1/697476
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 68,78,789 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,78,789) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(68,78,789) x common factors =1 x 6 = 6
LCM(68,78,789) = ( 68 × 78 × 789 ) / 6
LCM(68,78,789) = 4184856 / 6
LCM(68,78,789) = 697476
