Given numbers are 855,315,561,387,276

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

The LCM of 855,315,561,387,276 is 4427535420.

Find LCM of 855,315,561,387,276 with Prime Factorization

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

3 x 3 x 5 x 19 x 7 x 187 x 43 x 92 = 4427535420

Therefore, the lowest common multiple of 855,315,561,387,276 is 4427535420.

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.

855 x 315 x 561 x 387 x 276 = 16138366605900

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

561 : 1, 3, 11, 17, 33, 51, 187, 561

387 : 1, 3, 9, 43, 129, 387

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,315,561,387,276, is 3.

Now, the common factors can be found like this.

855:3x 3x 5x 19

315:3x 3x 5x 7

561:3x 11x 17

387:3x 3x 43

276:2x 2x 3x 23

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

3x 3x 3x 3x 3x 5 = 1215

Therefore, the value for common factors is 1215.

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 = 16138366605900/(3x1215)

LCM = 16138366605900/3645

LCM = 4427535420

Thus, we can understand that the LCM of 855,315,561,387,276 is 4427535420.
