Given numbers are 430,803,555,816,990

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

The LCM of 430,803,555,816,990 is 15637493520.

Find LCM of 430,803,555,816,990 with Prime Factorization

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

2 x 3 x 5 x 11 x 43 x 73 x 37 x 136 x 3 = 15637493520

Therefore, the lowest common multiple of 430,803,555,816,990 is 15637493520.

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.

430 x 803 x 555 x 816 x 990 = 154811185848000

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.

430 : 1, 2, 5, 10, 43, 86, 215, 430

803 : 1, 11, 73, 803

555 : 1, 3, 5, 15, 37, 111, 185, 555

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

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 430,803,555,816,990, is 1.

Now, the common factors can be found like this.

430:2x 5x 43

803:11x 73

555:3x 5x 37

816:2x 2x 2x 2x 3x 17

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 2x 3x 3x 5x 5x 11 = 9900

Therefore, the value for common factors is 9900.

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 = 154811185848000/(1x9900)

LCM = 154811185848000/9900

LCM = 15637493520

Thus, we can understand that the LCM of 430,803,555,816,990 is 15637493520.
