Given numbers are 723,715,334,638

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

The LCM of 723,715,334,638 is 5007129270.

Find LCM of 723,715,334,638 with Prime Factorization

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

2 x 11 x 723 x 65 x 167 x 29 = 5007129270

Therefore, the lowest common multiple of 723,715,334,638 is 5007129270.

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.

723 x 715 x 334 x 638 = 110156843940

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.

723 : 1, 3, 241, 723

715 : 1, 5, 11, 13, 55, 65, 143, 715

334 : 1, 2, 167, 334

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,715,334,638, is 1.

Now, the common factors can be found like this.

723:3x 241

715:5x 11x 13

334:2x 167

638:2x 11x 29

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 110156843940/(1x22)

LCM = 110156843940/22

LCM = 5007129270

Thus, we can understand that the LCM of 723,715,334,638 is 5007129270.
