Given numbers are 638,377,261,406

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

The LCM of 638,377,261,406 is 522522.

Find LCM of 638,377,261,406 with Prime Factorization

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

2 x 29 x 11 x 13 x 9 x 7 = 522522

Therefore, the lowest common multiple of 638,377,261,406 is 522522.

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.

638 x 377 x 261 x 406 = 25487578116

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

377 : 1, 13, 29, 377

261 : 1, 3, 9, 29, 87, 261

406 : 1, 2, 7, 14, 29, 58, 203, 406

29 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,377,261,406, is 29.

Now, the common factors can be found like this.

638:2x 11x 29

377:13x 29

261:3x 3x 29

406:2x 7x 29

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

2x 29x 29 = 1682

Therefore, the value for common factors is 1682.

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 = 25487578116/(29x1682)

LCM = 25487578116/48778

LCM = 522522

Thus, we can understand that the LCM of 638,377,261,406 is 522522.
