Given numbers are 928,900,821,530

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

The LCM of 928,900,821,530 is 9085514400.

Find LCM of 928,900,821,530 with Prime Factorization

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

2 x 2 x 5 x 232 x 45 x 821 x 53 = 9085514400

Therefore, the lowest common multiple of 928,900,821,530 is 9085514400.

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.

928 x 900 x 821 x 530 = 363420576000

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.

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

821 : 1, 821

530 : 1, 2, 5, 10, 53, 106, 265, 530

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,900,821,530, is 1.

Now, the common factors can be found like this.

928:2x 2x 2x 2x 2x 29

900:2x 2x 3x 3x 5x 5

821:821

530:2x 5x 53

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 5 = 40

Therefore, the value for common factors is 40.

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 = 363420576000/(1x40)

LCM = 363420576000/40

LCM = 9085514400

Thus, we can understand that the LCM of 928,900,821,530 is 9085514400.
