Given numbers are 855,911,317,561,247

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

The LCM of 855,911,317,561,247 is 600245223435.

Find LCM of 855,911,317,561,247 with Prime Factorization

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

3 x 19 x 15 x 911 x 317 x 187 x 13 = 600245223435

Therefore, the lowest common multiple of 855,911,317,561,247 is 600245223435.

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 911 x 317 x 561 x 247 = 34213977735795

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

911 : 1, 911

317 : 1, 317

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

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,911,317,561,247, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

911:911

317:317

561:3x 11x 17

247:13x 19

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 34213977735795/(1x57)

LCM = 34213977735795/57

LCM = 600245223435

Thus, we can understand that the LCM of 855,911,317,561,247 is 600245223435.
