Given numbers are 328,381,747,615

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

The LCM of 328,381,747,615 is 155585160.

Find LCM of 328,381,747,615 with Prime Factorization

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

3 x 41 x 8 x 127 x 249 x 5 = 155585160

Therefore, the lowest common multiple of 328,381,747,615 is 155585160.

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.

328 x 381 x 747 x 615 = 57410924040

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.

328 : 1, 2, 4, 8, 41, 82, 164, 328

381 : 1, 3, 127, 381

747 : 1, 3, 9, 83, 249, 747

615 : 1, 3, 5, 15, 41, 123, 205, 615

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,381,747,615, is 1.

Now, the common factors can be found like this.

328:2x 2x 2x 41

381:3x 127

747:3x 3x 83

615:3x 5x 41

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

3x 3x 41 = 369

Therefore, the value for common factors is 369.

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 = 57410924040/(1x369)

LCM = 57410924040/369

LCM = 155585160

Thus, we can understand that the LCM of 328,381,747,615 is 155585160.
