Given numbers are 380,331,551,286

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

The LCM of 380,331,551,286 is 521609660.

Find LCM of 380,331,551,286 with Prime Factorization

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

2 x 19 x 10 x 331 x 29 x 143 = 521609660

Therefore, the lowest common multiple of 380,331,551,286 is 521609660.

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 331 x 551 x 286 = 19821167080

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

331 : 1, 331

551 : 1, 19, 29, 551

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,331,551,286, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

331:331

551:19x 29

286:2x 11x 13

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 19821167080/(1x38)

LCM = 19821167080/38

LCM = 521609660

Thus, we can understand that the LCM of 380,331,551,286 is 521609660.
