Given numbers are 215,884,553,990

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

The LCM of 215,884,553,990 is 10405214820.

Find LCM of 215,884,553,990 with Prime Factorization

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

2 x 5 x 43 x 442 x 553 x 99 = 10405214820

Therefore, the lowest common multiple of 215,884,553,990 is 10405214820.

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.

215 x 884 x 553 x 990 = 104052148200

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.

215 : 1, 5, 43, 215

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

553 : 1, 7, 79, 553

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,884,553,990, is 1.

Now, the common factors can be found like this.

215:5x 43

884:2x 2x 13x 17

553:7x 79

990:2x 3x 3x 5x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 104052148200/(1x10)

LCM = 104052148200/10

LCM = 10405214820

Thus, we can understand that the LCM of 215,884,553,990 is 10405214820.
