Given numbers are 438,647,321,849

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

The LCM of 438,647,321,849 is 8581211466.

Find LCM of 438,647,321,849 with Prime Factorization

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

3 x 146 x 647 x 107 x 283 = 8581211466

Therefore, the lowest common multiple of 438,647,321,849 is 8581211466.

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.

438 x 647 x 321 x 849 = 77230903194

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.

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

647 : 1, 647

321 : 1, 3, 107, 321

849 : 1, 3, 283, 849

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,647,321,849, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

647:647

321:3x 107

849:3x 283

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 77230903194/(1x9)

LCM = 77230903194/9

LCM = 8581211466

Thus, we can understand that the LCM of 438,647,321,849 is 8581211466.
