Given numbers are 819,103,442

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

The LCM of 819,103,442 is 2868138.

Find LCM of 819,103,442 with Prime Factorization

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

13 x 63 x 103 x 34 = 2868138

Therefore, the lowest common multiple of 819,103,442 is 2868138.

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.

819 x 103 x 442 = 37285794

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.

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

103 : 1, 103

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,103,442, is 1.

Now, the common factors can be found like this.

819:3x 3x 7x 13

103:103

442:2x 13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 37285794/(1x13)

LCM = 37285794/13

LCM = 2868138

Thus, we can understand that the LCM of 819,103,442 is 2868138.

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

• LCM of 775, 474, 387
