So the greatest common factor 66,601,505 is 1.
Lets's calculate LCM of 77,85,285
5 | 77, 85, 285 |
77, 17, 57 |
∴ So the LCM of the given numbers is 5 x 77 x 17 x 57 = 373065
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/373065
Therefore, the GCF of Fractions 66/77,601/85,505/285 is 1/373065
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 77,85,285 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,85,285) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(77,85,285) x common factors =1 x 5 = 5
LCM(77,85,285) = ( 77 × 85 × 285 ) / 5
LCM(77,85,285) = 1865325 / 5
LCM(77,85,285) = 373065
