The first step in determining the Least Common Multiple of 280 and 288 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 280 and 288:
Lets look at the first ten multiples of these numbers, 280 and 288:
280,560,840,1120,1400,1680,1960,2240,2520,4760 are the first ten multiples of 280.
288,576,864,1152,1440,1728,2016,2304,2592,4896 are the first ten multiples of 288.
You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 280 and 288, for example, are 3360, 4760, and 4608. 10080 is the least common multiple since it is the smallest.
280 and 288 have an LCM of 10080.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 280 and 288, than apply into the LCM equation.
GCF(280,288) = 8
LCM(280,288) = ( 280 × 288) / 8
LCM(280,288) = 80640 / 8
LCM(280,288) = 10080
