Given numbers are 380,447,107,891

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

The LCM of 380,447,107,891 is 5397980940.

Find LCM of 380,447,107,891 with Prime Factorization

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

3 x 380 x 149 x 107 x 297 = 5397980940

Therefore, the lowest common multiple of 380,447,107,891 is 5397980940.

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.

380 x 447 x 107 x 891 = 16193942820

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.

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

447 : 1, 3, 149, 447

107 : 1, 107

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,447,107,891, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

447:3x 149

107:107

891:3x 3x 3x 3x 11

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

3 = 3

Therefore, the value for common factors is 3.

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 = 16193942820/(1x3)

LCM = 16193942820/3

LCM = 5397980940

Thus, we can understand that the LCM of 380,447,107,891 is 5397980940.
