Given numbers are 861,624,741,663,515

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

The LCM of 861,624,741,663,515 is 29790393360.

Find LCM of 861,624,741,663,515 with Prime Factorization

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

3 x 13 x 287 x 16 x 19 x 17 x 515 = 29790393360

Therefore, the lowest common multiple of 861,624,741,663,515 is 29790393360.

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.

861 x 624 x 741 x 663 x 515 = 135933564901680

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

741 : 1, 3, 13, 19, 39, 57, 247, 741

663 : 1, 3, 13, 17, 39, 51, 221, 663

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,624,741,663,515, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

624:2x 2x 2x 2x 3x 13

741:3x 13x 19

663:3x 13x 17

515:5x 103

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

3x 3x 3x 13x 13 = 4563

Therefore, the value for common factors is 4563.

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 = 135933564901680/(1x4563)

LCM = 135933564901680/4563

LCM = 29790393360

Thus, we can understand that the LCM of 861,624,741,663,515 is 29790393360.
