Given numbers are 396,130,397

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

The LCM of 396,130,397 is 10218780.

Find LCM of 396,130,397 with Prime Factorization

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

2 x 198 x 65 x 397 = 10218780

Therefore, the lowest common multiple of 396,130,397 is 10218780.

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.

396 x 130 x 397 = 20437560

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.

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

130 : 1, 2, 5, 10, 13, 26, 65, 130

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,130,397, is 1.

Now, the common factors can be found like this.

396:2x 2x 3x 3x 11

130:2x 5x 13

397:397

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 = 20437560/(1x2)

LCM = 20437560/2

LCM = 10218780

Thus, we can understand that the LCM of 396,130,397 is 10218780.

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

• LCM of 384, 111, 381
