So the greatest common factor 69,79,165 is 1.
Lets's calculate LCM of 125,405,917
5 | 125, 405, 917 |
25, 81, 917 |
∴ So the LCM of the given numbers is 5 x 25 x 81 x 917 = 9284625
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9284625
Therefore, the GCF of Fractions 69/125,79/405,165/917 is 1/9284625
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 125,405,917 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(125,405,917) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(125,405,917) x common factors =1 x 5 = 5
LCM(125,405,917) = ( 125 × 405 × 917 ) / 5
LCM(125,405,917) = 46423125 / 5
LCM(125,405,917) = 9284625
