Given numbers are 842,520,289,809

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

The LCM of 842,520,289,809 is 51183714920.

Find LCM of 842,520,289,809 with Prime Factorization

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

2 x 421 x 260 x 289 x 809 = 51183714920

Therefore, the lowest common multiple of 842,520,289,809 is 51183714920.

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.

842 x 520 x 289 x 809 = 102367429840

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.

842 : 1, 2, 421, 842

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

289 : 1, 17, 289

809 : 1, 809

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,520,289,809, is 1.

Now, the common factors can be found like this.

842:2x 421

520:2x 2x 2x 5x 13

289:17x 17

809:809

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 102367429840/(1x2)

LCM = 102367429840/2

LCM = 51183714920

Thus, we can understand that the LCM of 842,520,289,809 is 51183714920.
