Given numbers are 128,366,640,498

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

The LCM of 128,366,640,498 is 9720960.

Find LCM of 128,366,640,498 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 1 x 61 x 5 x 83 = 9720960

Therefore, the lowest common multiple of 128,366,640,498 is 9720960.

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.

128 x 366 x 640 x 498 = 14931394560

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

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

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

498 : 1, 2, 3, 6, 83, 166, 249, 498

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,366,640,498, is 2.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

366:2x 3x 61

640:2x 2x 2x 2x 2x 2x 2x 5

498:2x 3x 83

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 2x 2x 2x 2x 2x 2x 3 = 768

Therefore, the value for common factors is 768.

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 = 14931394560/(2x768)

LCM = 14931394560/1536

LCM = 9720960

Thus, we can understand that the LCM of 128,366,640,498 is 9720960.
