Given numbers are 747,638,460

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

The LCM of 747,638,460 is 109614780.

Find LCM of 747,638,460 with Prime Factorization

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

2 x 747 x 319 x 230 = 109614780

Therefore, the lowest common multiple of 747,638,460 is 109614780.

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.

747 x 638 x 460 = 219229560

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.

747 : 1, 3, 9, 83, 249, 747

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

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,638,460, is 1.

Now, the common factors can be found like this.

747:3x 3x 83

638:2x 11x 29

460:2x 2x 5x 23

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

2 = 2

Therefore, the value for common factors is 2.

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 = 219229560/(1x2)

LCM = 219229560/2

LCM = 109614780

Thus, we can understand that the LCM of 747,638,460 is 109614780.
