Multiples of 238 =238,476,714,952,1190,1428,1666,1904,2142,2380,2618,2856,3094,3332,3570,3808,4046,

Multiples of 242 =242,484,726,968,1210,1452,1694,1936,2178,2420,2662,2904,3146,3388,3630,3872,4114,

Now, get the least common multiple of 238, 242 which is 28798

So, the LCM of 238, 242 is 28798.

One method for determining the LCM of 238 and 242 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 238's prime factorization:

Prime factors of 238 are 2, 7,17.

238 = 2¹×7¹×17¹

And this is 242's prime factorization:

Prime factors of 242 are 2,11.

242 = 2¹×11²

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, 7,17,11

2¹×7¹×11²×17¹ = 28798

This shows that the LCM of 238 and 242 is 28798.

The first step in determining the Least Common Multiple of 238 and 242 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 238 and 242:

Lets look at the first ten multiples of these numbers, 238 and 242:

238,476,714,952,1190,1428,1666,1904,2142,4046 are the first ten multiples of 238.

242,484,726,968,1210,1452,1694,1936,2178,4114 are the first ten multiples of 242.

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 238 and 242, for example, are 2856, 4046, and 3872. 28798 is the least common multiple since it is the smallest.

238 and 242 have an LCM of 28798.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 238 and 242, than apply into the LCM equation.

GCF(238,242) = 2
LCM(238,242) = ( 238 × 242) / 2
LCM(238,242) = 57596 / 2
LCM(238,242) = 28798
