Given numbers are 518,217,703,287

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

The LCM of 518,217,703,287 is 12509182.

Find LCM of 518,217,703,287 with Prime Factorization

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

7 x 37 x 2 x 31 x 19 x 41 = 12509182

Therefore, the lowest common multiple of 518,217,703,287 is 12509182.

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.

518 x 217 x 703 x 287 = 22679146966

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.

518 : 1, 2, 7, 14, 37, 74, 259, 518

217 : 1, 7, 31, 217

703 : 1, 19, 37, 703

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,217,703,287, is 1.

Now, the common factors can be found like this.

518:2x 7x 37

217:7x 31

703:19x 37

287:7x 41

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

7x 7x 37 = 1813

Therefore, the value for common factors is 1813.

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 = 22679146966/(1x1813)

LCM = 22679146966/1813

LCM = 12509182

Thus, we can understand that the LCM of 518,217,703,287 is 12509182.
