Given numbers are 489,371,720,203

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

The LCM of 489,371,720,203 is 1262676240.

Find LCM of 489,371,720,203 with Prime Factorization

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

3 x 7 x 163 x 53 x 240 x 29 = 1262676240

Therefore, the lowest common multiple of 489,371,720,203 is 1262676240.

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 371 x 720 x 203 = 26516201040

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

371 : 1, 7, 53, 371

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,371,720,203, is 1.

Now, the common factors can be found like this.

489:3x 163

371:7x 53

720:2x 2x 2x 2x 3x 3x 5

203:7x 29

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 26516201040/(1x21)

LCM = 26516201040/21

LCM = 1262676240

Thus, we can understand that the LCM of 489,371,720,203 is 1262676240.

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