Given numbers are 800,880,386,455

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

The LCM of 800,880,386,455 is 154554400.

Find LCM of 800,880,386,455 with Prime Factorization

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

2 x 2 x 2 x 2 x 5 x 10 x 11 x 193 x 91 = 154554400

Therefore, the lowest common multiple of 800,880,386,455 is 154554400.

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.

800 x 880 x 386 x 455 = 123643520000

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.

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

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

386 : 1, 2, 193, 386

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,880,386,455, is 1.

Now, the common factors can be found like this.

800:2x 2x 2x 2x 2x 5x 5

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

386:2x 193

455:5x 7x 13

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 5x 5 = 800

Therefore, the value for common factors is 800.

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 = 123643520000/(1x800)

LCM = 123643520000/800

LCM = 154554400

Thus, we can understand that the LCM of 800,880,386,455 is 154554400.
