Given numbers are 361,289,720,563,915

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

The LCM of 361,289,720,563,915 is 2579739009840.

Find LCM of 361,289,720,563,915 with Prime Factorization

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

3 x 5 x 361 x 289 x 48 x 563 x 61 = 2579739009840

Therefore, the lowest common multiple of 361,289,720,563,915 is 2579739009840.

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.

361 x 289 x 720 x 563 x 915 = 38696085147600

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.

361 : 1, 19, 361

289 : 1, 17, 289

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

563 : 1, 563

915 : 1, 3, 5, 15, 61, 183, 305, 915

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,289,720,563,915, is 1.

Now, the common factors can be found like this.

361:19x 19

289:17x 17

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

563:563

915:3x 5x 61

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 38696085147600/(1x15)

LCM = 38696085147600/15

LCM = 2579739009840

Thus, we can understand that the LCM of 361,289,720,563,915 is 2579739009840.
