Given numbers are 489,1368

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

The LCM of 489,1368 is 222984.

Find LCM of 489,1368 with Prime Factorization

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

3 x 163 x 456 = 222984

Therefore, the lowest common multiple of 489,1368 is 222984.

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.

489 x 1368 = 668952

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.

489 : 1, 3, 163, 489

1368 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 19, 24, 36, 38, 57, 72, 76, 114, 152, 171, 228, 342, 456, 684, 1368

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,1368, is 3.

Now, the common factors can be found like this.

489:3x 163

1368:2x 2x 2x 3x 3x 19

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

= 1

Therefore, the value for common factors is 1.

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 = 668952/(3x1)

LCM = 668952/3

LCM = 222984

Thus, we can understand that the LCM of 489,1368 is 222984.

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

• LCM of 205, 5239
• LCM of 871, 6896
