Given numbers are 291,842,666,391

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

The LCM of 291,842,666,391 is 10634199822.

Find LCM of 291,842,666,391 with Prime Factorization

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

2 x 3 x 97 x 421 x 111 x 391 = 10634199822

Therefore, the lowest common multiple of 291,842,666,391 is 10634199822.

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 666 x 391 = 63805198932

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

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,842,666,391, is 1.

Now, the common factors can be found like this.

291:3x 97

842:2x 421

666:2x 3x 3x 37

391:17x 23

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 63805198932/(1x6)

LCM = 63805198932/6

LCM = 10634199822

Thus, we can understand that the LCM of 291,842,666,391 is 10634199822.
