Given numbers are 380,817,862,388

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

The LCM of 380,817,862,388 is 683126380.

Find LCM of 380,817,862,388 with Prime Factorization

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

2 x 2 x 19 x 5 x 43 x 431 x 97 = 683126380

Therefore, the lowest common multiple of 380,817,862,388 is 683126380.

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 817 x 862 x 388 = 103835209760

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

817 : 1, 19, 43, 817

862 : 1, 2, 431, 862

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,817,862,388, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

817:19x 43

862:2x 431

388:2x 2x 97

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

2x 2x 2x 19 = 152

Therefore, the value for common factors is 152.

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 = 103835209760/(1x152)

LCM = 103835209760/152

LCM = 683126380

Thus, we can understand that the LCM of 380,817,862,388 is 683126380.
