Given numbers are 381,489,249,172

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

The LCM of 381,489,249,172 is 886582428.

Find LCM of 381,489,249,172 with Prime Factorization

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

3 x 127 x 163 x 83 x 172 = 886582428

Therefore, the lowest common multiple of 381,489,249,172 is 886582428.

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.

381 x 489 x 249 x 172 = 7979241852

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.

381 : 1, 3, 127, 381

489 : 1, 3, 163, 489

249 : 1, 3, 83, 249

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,489,249,172, is 1.

Now, the common factors can be found like this.

381:3x 127

489:3x 163

249:3x 83

172:2x 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.

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 = 7979241852/(1x9)

LCM = 7979241852/9

LCM = 886582428

Thus, we can understand that the LCM of 381,489,249,172 is 886582428.
