Given numbers are 643,376,862,207,474

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

The LCM of 643,376,862,207,474 is 1704015436824.

Find LCM of 643,376,862,207,474 with Prime Factorization

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

2 x 3 x 643 x 188 x 431 x 69 x 79 = 1704015436824

Therefore, the lowest common multiple of 643,376,862,207,474 is 1704015436824.

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.

643 x 376 x 862 x 207 x 474 = 20448185241888

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.

643 : 1, 643

376 : 1, 2, 4, 8, 47, 94, 188, 376

862 : 1, 2, 431, 862

207 : 1, 3, 9, 23, 69, 207

474 : 1, 2, 3, 6, 79, 158, 237, 474

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,376,862,207,474, is 1.

Now, the common factors can be found like this.

643:643

376:2x 2x 2x 47

862:2x 431

207:3x 3x 23

474:2x 3x 79

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 20448185241888/(1x12)

LCM = 20448185241888/12

LCM = 1704015436824

Thus, we can understand that the LCM of 643,376,862,207,474 is 1704015436824.
