Given numbers are 322,18,447

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

The LCM of 322,18,447 is 431802.

Find LCM of 322,18,447 with Prime Factorization

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

2 x 3 x 161 x 3 x 149 = 431802

Therefore, the lowest common multiple of 322,18,447 is 431802.

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.

322 x 18 x 447 = 2590812

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.

322 : 1, 2, 7, 14, 23, 46, 161, 322

18 : 1, 2, 3, 6, 9, 18

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,18,447, is 1.

Now, the common factors can be found like this.

322:2x 7x 23

18:2x 3x 3

447:3x 149

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 2590812/(1x6)

LCM = 2590812/6

LCM = 431802

Thus, we can understand that the LCM of 322,18,447 is 431802.

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

• LCM of 863, 61, 611
• LCM of 271, 27, 630
