Given numbers are 684,866,454,890

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

The LCM of 684,866,454,890 is 29917814580.

Find LCM of 684,866,454,890 with Prime Factorization

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

2 x 342 x 433 x 227 x 445 = 29917814580

Therefore, the lowest common multiple of 684,866,454,890 is 29917814580.

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.

684 x 866 x 454 x 890 = 239342516640

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.

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

866 : 1, 2, 433, 866

454 : 1, 2, 227, 454

890 : 1, 2, 5, 10, 89, 178, 445, 890

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,866,454,890, is 2.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

866:2x 433

454:2x 227

890:2x 5x 89

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 239342516640/(2x4)

LCM = 239342516640/8

LCM = 29917814580

Thus, we can understand that the LCM of 684,866,454,890 is 29917814580.
