Given numbers are 821,717,544,928

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

The LCM of 821,717,544,928 is 9286652832.

Find LCM of 821,717,544,928 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 821 x 717 x 17 x 29 = 9286652832

Therefore, the lowest common multiple of 821,717,544,928 is 9286652832.

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.

821 x 717 x 544 x 928 = 297172890624

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.

821 : 1, 821

717 : 1, 3, 239, 717

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,717,544,928, is 1.

Now, the common factors can be found like this.

821:821

717:3x 239

544:2x 2x 2x 2x 2x 17

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

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 2 = 32

Therefore, the value for common factors is 32.

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 = 297172890624/(1x32)

LCM = 297172890624/32

LCM = 9286652832

Thus, we can understand that the LCM of 821,717,544,928 is 9286652832.
