Given numbers are 260,405,643,907

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

The LCM of 260,405,643,907 is 12282213060.

Find LCM of 260,405,643,907 with Prime Factorization

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

5 x 52 x 81 x 643 x 907 = 12282213060

Therefore, the lowest common multiple of 260,405,643,907 is 12282213060.

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.

260 x 405 x 643 x 907 = 61411065300

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.

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

643 : 1, 643

907 : 1, 907

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,405,643,907, is 1.

Now, the common factors can be found like this.

260:2x 2x 5x 13

405:3x 3x 3x 3x 5

643:643

907:907

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

5 = 5

Therefore, the value for common factors is 5.

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 = 61411065300/(1x5)

LCM = 61411065300/5

LCM = 12282213060

Thus, we can understand that the LCM of 260,405,643,907 is 12282213060.
