Given numbers are 818,418,438,344

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

The LCM of 818,418,438,344 is 6439796616.

Find LCM of 818,418,438,344 with Prime Factorization

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

2 x 409 x 209 x 219 x 172 = 6439796616

Therefore, the lowest common multiple of 818,418,438,344 is 6439796616.

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.

818 x 418 x 438 x 344 = 51518372928

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.

818 : 1, 2, 409, 818

418 : 1, 2, 11, 19, 22, 38, 209, 418

438 : 1, 2, 3, 6, 73, 146, 219, 438

344 : 1, 2, 4, 8, 43, 86, 172, 344

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,418,438,344, is 2.

Now, the common factors can be found like this.

818:2x 409

418:2x 11x 19

438:2x 3x 73

344:2x 2x 2x 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 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 = 51518372928/(2x4)

LCM = 51518372928/8

LCM = 6439796616

Thus, we can understand that the LCM of 818,418,438,344 is 6439796616.
