Given numbers are 291,842,816,561,867

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

The LCM of 291,842,816,561,867 is 6231399504.

Find LCM of 291,842,816,561,867 with Prime Factorization

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

2 x 3 x 17 x 97 x 421 x 8 x 11 x 17 = 6231399504

Therefore, the lowest common multiple of 291,842,816,561,867 is 6231399504.

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.

291 x 842 x 816 x 561 x 867 = 97247220659424

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.

291 : 1, 3, 97, 291

842 : 1, 2, 421, 842

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

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

867 : 1, 3, 17, 51, 289, 867

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,842,816,561,867, is 1.

Now, the common factors can be found like this.

291:3x 97

842:2x 421

816:2x 2x 2x 2x 3x 17

561:3x 11x 17

867:3x 17x 17

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

2x 3x 3x 3x 17x 17 = 15606

Therefore, the value for common factors is 15606.

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 = 97247220659424/(1x15606)

LCM = 97247220659424/15606

LCM = 6231399504

Thus, we can understand that the LCM of 291,842,816,561,867 is 6231399504.
