Given numbers are 558,249,218,645

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

The LCM of 558,249,218,645 is 1085368590.

Find LCM of 558,249,218,645 with Prime Factorization

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

2 x 3 x 93 x 83 x 109 x 215 = 1085368590

Therefore, the lowest common multiple of 558,249,218,645 is 1085368590.

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.

558 x 249 x 218 x 645 = 19536634620

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.

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

249 : 1, 3, 83, 249

218 : 1, 2, 109, 218

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,249,218,645, is 1.

Now, the common factors can be found like this.

558:2x 3x 3x 31

249:3x 83

218:2x 109

645:3x 5x 43

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 19536634620/(1x18)

LCM = 19536634620/18

LCM = 1085368590

Thus, we can understand that the LCM of 558,249,218,645 is 1085368590.
