Given numbers are 720,410,581,698

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

The LCM of 720,410,581,698 is 5985740880.

Find LCM of 720,410,581,698 with Prime Factorization

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

2 x 5 x 72 x 41 x 581 x 349 = 5985740880

Therefore, the lowest common multiple of 720,410,581,698 is 5985740880.

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.

720 x 410 x 581 x 698 = 119714817600

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

410 : 1, 2, 5, 10, 41, 82, 205, 410

581 : 1, 7, 83, 581

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,410,581,698, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

410:2x 5x 41

581:7x 83

698:2x 349

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 119714817600/(1x20)

LCM = 119714817600/20

LCM = 5985740880

Thus, we can understand that the LCM of 720,410,581,698 is 5985740880.
