Given numbers are 618,249,715,412,642

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

The LCM of 618,249,715,412,642 is 7848494940.

Find LCM of 618,249,715,412,642 with Prime Factorization

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

2 x 3 x 103 x 1 x 83 x 715 x 2 x 107 = 7848494940

Therefore, the lowest common multiple of 618,249,715,412,642 is 7848494940.

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.

618 x 249 x 715 x 412 x 642 = 29102219237520

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.

618 : 1, 2, 3, 6, 103, 206, 309, 618

249 : 1, 3, 83, 249

715 : 1, 5, 11, 13, 55, 65, 143, 715

412 : 1, 2, 4, 103, 206, 412

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,249,715,412,642, is 1.

Now, the common factors can be found like this.

618:2x 3x 103

249:3x 83

715:5x 11x 13

412:2x 2x 103

642:2x 3x 107

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

2x 2x 3x 3x 103 = 3708

Therefore, the value for common factors is 3708.

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 = 29102219237520/(1x3708)

LCM = 29102219237520/3708

LCM = 7848494940

Thus, we can understand that the LCM of 618,249,715,412,642 is 7848494940.
