Given numbers are 643,299,689,271,491

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

The LCM of 643,299,689,271,491 is 1355841159881.

Find LCM of 643,299,689,271,491 with Prime Factorization

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

13 x 643 x 23 x 53 x 271 x 491 = 1355841159881

Therefore, the lowest common multiple of 643,299,689,271,491 is 1355841159881.

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 299 x 689 x 271 x 491 = 17625935078453

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

299 : 1, 13, 23, 299

689 : 1, 13, 53, 689

271 : 1, 271

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,299,689,271,491, is 1.

Now, the common factors can be found like this.

643:643

299:13x 23

689:13x 53

271:271

491:491

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

13 = 13

Therefore, the value for common factors is 13.

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 = 17625935078453/(1x13)

LCM = 17625935078453/13

LCM = 1355841159881

Thus, we can understand that the LCM of 643,299,689,271,491 is 1355841159881.
