Given numbers are 667,361,855,442

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

The LCM of 667,361,855,442 is 4789253430.

Find LCM of 667,361,855,442 with Prime Factorization

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

19 x 667 x 19 x 45 x 442 = 4789253430

Therefore, the lowest common multiple of 667,361,855,442 is 4789253430.

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.

667 x 361 x 855 x 442 = 90995815170

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.

667 : 1, 23, 29, 667

361 : 1, 19, 361

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

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,361,855,442, is 1.

Now, the common factors can be found like this.

667:23x 29

361:19x 19

855:3x 3x 5x 19

442:2x 13x 17

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

19 = 19

Therefore, the value for common factors is 19.

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 = 90995815170/(1x19)

LCM = 90995815170/19

LCM = 4789253430

Thus, we can understand that the LCM of 667,361,855,442 is 4789253430.
