Calculate the LCM of 331,342,830

Given numbers are 331,342,830

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 331,342,830 is 46978830.

Find LCM of 331,342,830 with Prime Factorization


2 331, 342, 830
331, 171, 415

Multiply the prime numbers at the bottom and the left side.

2 x 331 x 171 x 415 = 46978830

Therefore, the lowest common multiple of 331,342,830 is 46978830.

LCM Formula to Find Lowest Common Multiple of 331,342,830

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

331 x 342 x 830 = 93957660

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

331 : 1, 331

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

830 : 1, 2, 5, 10, 83, 166, 415, 830

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,342,830, is 1.

Now, the common factors can be found like this.

331:331

342:2x 3x 3x 19

830:2x 5x 83

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 93957660/(1x2)

LCM = 93957660/2

LCM = 46978830

Thus, we can understand that the LCM of 331,342,830 is 46978830.
