Given numbers are 990,880,455,404

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

The LCM of 990,880,455,404 is 72792720.

Find LCM of 990,880,455,404 with Prime Factorization

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

2 x 2 x 5 x 11 x 9 x 4 x 91 x 101 = 72792720

Therefore, the lowest common multiple of 990,880,455,404 is 72792720.

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.

990 x 880 x 455 x 404 = 160143984000

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.

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

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

455 : 1, 5, 7, 13, 35, 65, 91, 455

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,880,455,404, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

880:2x 2x 2x 2x 5x 11

455:5x 7x 13

404:2x 2x 101

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 5x 5x 11 = 2200

Therefore, the value for common factors is 2200.

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 = 160143984000/(1x2200)

LCM = 160143984000/2200

LCM = 72792720

Thus, we can understand that the LCM of 990,880,455,404 is 72792720.
