Given numbers are 721,572,366,215,898

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

The LCM of 721,572,366,215,898 is 7285631212860.

Find LCM of 721,572,366,215,898 with Prime Factorization

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

2 x 721 x 286 x 183 x 215 x 449 = 7285631212860

Therefore, the lowest common multiple of 721,572,366,215,898 is 7285631212860.

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.

721 x 572 x 366 x 215 x 898 = 29142524851440

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.

721 : 1, 7, 103, 721

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

366 : 1, 2, 3, 6, 61, 122, 183, 366

215 : 1, 5, 43, 215

898 : 1, 2, 449, 898

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,572,366,215,898, is 1.

Now, the common factors can be found like this.

721:7x 103

572:2x 2x 11x 13

366:2x 3x 61

215:5x 43

898:2x 449

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 = 29142524851440/(1x4)

LCM = 29142524851440/4

LCM = 7285631212860

Thus, we can understand that the LCM of 721,572,366,215,898 is 7285631212860.
