Given numbers are 443,721,664,260

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

The LCM of 443,721,664,260 is 13785433480.

Find LCM of 443,721,664,260 with Prime Factorization

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

2 x 2 x 443 x 721 x 166 x 65 = 13785433480

Therefore, the lowest common multiple of 443,721,664,260 is 13785433480.

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.

443 x 721 x 664 x 260 = 55141733920

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.

443 : 1, 443

721 : 1, 7, 103, 721

664 : 1, 2, 4, 8, 83, 166, 332, 664

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 443,721,664,260, is 1.

Now, the common factors can be found like this.

443:443

721:7x 103

664:2x 2x 2x 83

260:2x 2x 5x 13

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 55141733920/(1x4)

LCM = 55141733920/4

LCM = 13785433480

Thus, we can understand that the LCM of 443,721,664,260 is 13785433480.
