Given Numbers are 286, 290

We can find the LCM of 286, 290 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 286 and 290

Multiples of 286 =286,572,858,1144,1430,1716,2002,2288,2574,2860,3146,3432,3718,4004,4290,4576,4862,

Multiples of 290 =290,580,870,1160,1450,1740,2030,2320,2610,2900,3190,3480,3770,4060,4350,4640,4930,

Now, get the least common multiple of 286, 290 which is 41470

So, the LCM of 286, 290 is 41470.

One method for determining the LCM of 286 and 290 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:

Here is 286's prime factorization:

Prime factors of 286 are 2, 11,13.

286 = 2¹×11¹×13¹

And this is 290's prime factorization:

Prime factors of 290 are 2, 5,29.

290 = 2¹×5¹×29¹

When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered: 2, 11,13, 5,29

2¹×5¹×11¹×13¹×29¹ = 41470

This shows that the LCM of 286 and 290 is 41470.

The first step in determining the Least Common Multiple of 286 and 290 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 286 and 290:

Lets look at the first ten multiples of these numbers, 286 and 290:

286,572,858,1144,1430,1716,2002,2288,2574,4862 are the first ten multiples of 286.

290,580,870,1160,1450,1740,2030,2320,2610,4930 are the first ten multiples of 290.

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 286 and 290, for example, are 3432, 4862, and 4640. 41470 is the least common multiple since it is the smallest.

286 and 290 have an LCM of 41470.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 286 and 290, than apply into the LCM equation.

GCF(286,290) = 2
LCM(286,290) = ( 286 × 290) / 2
LCM(286,290) = 82940 / 2
LCM(286,290) = 41470
