Given numbers are 813,215,542

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

The LCM of 813,215,542 is 349590.

Find LCM of 813,215,542 with Prime Factorization

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

271 x 3 x 215 x 2 = 349590

Therefore, the lowest common multiple of 813,215,542 is 349590.

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.

813 x 215 x 542 = 94738890

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.

813 : 1, 3, 271, 813

215 : 1, 5, 43, 215

542 : 1, 2, 271, 542

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,215,542, is 1.

Now, the common factors can be found like this.

813:3x 271

215:5x 43

542:2x 271

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

271 = 271

Therefore, the value for common factors is 271.

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 = 94738890/(1x271)

LCM = 94738890/271

LCM = 349590

Thus, we can understand that the LCM of 813,215,542 is 349590.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 392, 680, 740
• LCM of 135, 362, 248
