Given numbers are 643,351,299,623

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

The LCM of 643,351,299,623 is 3233954997.

Find LCM of 643,351,299,623 with Prime Factorization

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

13 x 643 x 27 x 23 x 623 = 3233954997

Therefore, the lowest common multiple of 643,351,299,623 is 3233954997.

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 351 x 299 x 623 = 42041414961

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

351 : 1, 3, 9, 13, 27, 39, 117, 351

299 : 1, 13, 23, 299

623 : 1, 7, 89, 623

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,351,299,623, is 1.

Now, the common factors can be found like this.

643:643

351:3x 3x 3x 13

299:13x 23

623:7x 89

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 = 42041414961/(1x13)

LCM = 42041414961/13

LCM = 3233954997

Thus, we can understand that the LCM of 643,351,299,623 is 3233954997.
