List of positive integer factors of 2440 that divides 2440 without a remainder.
1,2,4,5,8,10,20,40,61,122,244,305,488,610,1220,2440
Greatest Common Factor
We found the factors 65,2440 . The biggest common factor number is the GCF number.
So the greatest common factor 65,2440 is 5.
Lets's calculate LCM of 280,2141
Given numbers has no common factors except 1. So, there LCM is their product i.e 599480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/599480
Therefore, the GCF of Fractions 65/280,2440/2141 is 5/599480
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 280,2141 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(280,2141) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(280,2141) x common factors =1 x 1 = 1
LCM(280,2141) = ( 280 × 2141 ) / 1
LCM(280,2141) = 599480 / 1
LCM(280,2141) = 599480
