Given numbers are 561,440,899

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

The LCM of 561,440,899 is 20173560.

Find LCM of 561,440,899 with Prime Factorization

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

11 x 51 x 40 x 899 = 20173560

Therefore, the lowest common multiple of 561,440,899 is 20173560.

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.

561 x 440 x 899 = 221909160

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

899 : 1, 29, 31, 899

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,440,899, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

440:2x 2x 2x 5x 11

899:29x 31

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

11 = 11

Therefore, the value for common factors is 11.

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 = 221909160/(1x11)

LCM = 221909160/11

LCM = 20173560

Thus, we can understand that the LCM of 561,440,899 is 20173560.
