Given numbers are 381,451,575,670

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

The LCM of 381,451,575,670 is 13239578550.

Find LCM of 381,451,575,670 with Prime Factorization

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

5 x 381 x 451 x 115 x 134 = 13239578550

Therefore, the lowest common multiple of 381,451,575,670 is 13239578550.

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 451 x 575 x 670 = 66197892750

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

451 : 1, 11, 41, 451

575 : 1, 5, 23, 25, 115, 575

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,451,575,670, is 1.

Now, the common factors can be found like this.

381:3x 127

451:11x 41

575:5x 5x 23

670:2x 5x 67

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

5 = 5

Therefore, the value for common factors is 5.

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 = 66197892750/(1x5)

LCM = 66197892750/5

LCM = 13239578550

Thus, we can understand that the LCM of 381,451,575,670 is 13239578550.
