Given numbers are 381,291,388,698

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

The LCM of 381,291,388,698 is 51591972.

Find LCM of 381,291,388,698 with Prime Factorization

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

2 x 3 x 97 x 127 x 1 x 2 x 349 = 51591972

Therefore, the lowest common multiple of 381,291,388,698 is 51591972.

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 291 x 388 x 698 = 30026527704

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

291 : 1, 3, 97, 291

388 : 1, 2, 4, 97, 194, 388

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,291,388,698, is 1.

Now, the common factors can be found like this.

381:3x 127

291:3x 97

388:2x 2x 97

698:2x 349

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

2x 3x 97 = 582

Therefore, the value for common factors is 582.

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 = 30026527704/(1x582)

LCM = 30026527704/582

LCM = 51591972

Thus, we can understand that the LCM of 381,291,388,698 is 51591972.
