Given numbers are 7,287,581,819

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

The LCM of 7,287,581,819 is 2787057.

Find LCM of 7,287,581,819 with Prime Factorization

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

7 x 1 x 41 x 83 x 117 = 2787057

Therefore, the lowest common multiple of 7,287,581,819 is 2787057.

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.

7 x 287 x 581 x 819 = 955960551

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.

7 : 1, 7

287 : 1, 7, 41, 287

581 : 1, 7, 83, 581

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,287,581,819, is 7.

Now, the common factors can be found like this.

7:7

287:7x 41

581:7x 83

819:3x 3x 7x 13

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 955960551/(7x49)

LCM = 955960551/343

LCM = 2787057

Thus, we can understand that the LCM of 7,287,581,819 is 2787057.
