Given numbers are 380,643,269,920

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

The LCM of 380,643,269,920 is 3023463160.

Find LCM of 380,643,269,920 with Prime Factorization

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

2 x 2 x 5 x 19 x 643 x 269 x 46 = 3023463160

Therefore, the lowest common multiple of 380,643,269,920 is 3023463160.

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 643 x 269 x 920 = 60469263200

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

643 : 1, 643

269 : 1, 269

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,643,269,920, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

643:643

269:269

920:2x 2x 2x 5x 23

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 5 = 20

Therefore, the value for common factors is 20.

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 = 60469263200/(1x20)

LCM = 60469263200/20

LCM = 3023463160

Thus, we can understand that the LCM of 380,643,269,920 is 3023463160.
