Given numbers are 424,242,643,830

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

The LCM of 424,242,643,830 is 13690215880.

Find LCM of 424,242,643,830 with Prime Factorization

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

2 x 212 x 121 x 643 x 415 = 13690215880

Therefore, the lowest common multiple of 424,242,643,830 is 13690215880.

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.

424 x 242 x 643 x 830 = 54760863520

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.

424 : 1, 2, 4, 8, 53, 106, 212, 424

242 : 1, 2, 11, 22, 121, 242

643 : 1, 643

830 : 1, 2, 5, 10, 83, 166, 415, 830

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,242,643,830, is 1.

Now, the common factors can be found like this.

424:2x 2x 2x 53

242:2x 11x 11

643:643

830:2x 5x 83

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 54760863520/(1x4)

LCM = 54760863520/4

LCM = 13690215880

Thus, we can understand that the LCM of 424,242,643,830 is 13690215880.
