Given Numbers are 34, 42

We can find the LCM of 34, 42 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 34 and 42

Multiples of 34 =34,68,102,136,170,204,238,272,306,340,374,408,442,476,510,544,578,

Multiples of 42 =42,84,126,168,210,252,294,336,378,420,462,504,546,588,630,672,714,

Now, get the least common multiple of 34, 42 which is 714

So, the LCM of 34, 42 is 714.

One method for determining the LCM of 34 and 42 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 34's prime factorization:

Prime factors of 34 are 2,17.

34 = 2¹×17¹

And this is 42's prime factorization:

Prime factors of 42 are 2, 3,7.

42 = 2¹×3¹×7¹

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: 2,17, 3,7

2¹×3¹×7¹×17¹ = 714

This shows that the LCM of 34 and 42 is 714.

The first step in determining the Least Common Multiple of 34 and 42 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 34 and 42:

Lets look at the first ten multiples of these numbers, 34 and 42:

34,68,102,136,170,204,238,272,306,578 are the first ten multiples of 34.

42,84,126,168,210,252,294,336,378,714 are the first ten multiples of 42.

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 34 and 42, for example, are 408, 578, and 672. 714 is the least common multiple since it is the smallest.

34 and 42 have an LCM of 714.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 34 and 42, than apply into the LCM equation.

GCF(34,42) = 2
LCM(34,42) = ( 34 × 42) / 2
LCM(34,42) = 1428 / 2
LCM(34,42) = 714
