Factors of 353
List of positive integer factors of 353 that divides 353 without a remainder.
1,353
Greatest Common Factor
We found the factors 390,635,353 . The biggest common factor number is the GCF number.
So the greatest common factor 390,635,353 is 1.
Lets's calculate LCM of 23,33,40
Given numbers has no common factors except 1. So, there LCM is their product i.e 30360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30360
Therefore, the GCF of Fractions 390/23,635/33,353/40 is 1/30360
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 23,33,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,33,40) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,33,40) x common factors =1 x 1 = 1
LCM(23,33,40) = ( 23 × 33 × 40 ) / 1
LCM(23,33,40) = 30360 / 1
LCM(23,33,40) = 30360
