Given numbers are 667,886,398,391

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

The LCM of 667,886,398,391 is 1999224446.

Find LCM of 667,886,398,391 with Prime Factorization

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

2 x 23 x 29 x 443 x 199 x 17 = 1999224446

Therefore, the lowest common multiple of 667,886,398,391 is 1999224446.

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 886 x 398 x 391 = 91964324516

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

886 : 1, 2, 443, 886

398 : 1, 2, 199, 398

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,886,398,391, is 1.

Now, the common factors can be found like this.

667:23x 29

886:2x 443

398:2x 199

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 23 = 46

Therefore, the value for common factors is 46.

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 = 91964324516/(1x46)

LCM = 91964324516/46

LCM = 1999224446

Thus, we can understand that the LCM of 667,886,398,391 is 1999224446.
