Given numbers are 638,404,176,880

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

The LCM of 638,404,176,880 is 2577520.

Find LCM of 638,404,176,880 with Prime Factorization

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

2 x 2 x 2 x 2 x 11 x 29 x 101 x 1 x 5 = 2577520

Therefore, the lowest common multiple of 638,404,176,880 is 2577520.

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 404 x 176 x 880 = 39920629760

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

404 : 1, 2, 4, 101, 202, 404

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,404,176,880, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

404:2x 2x 101

176:2x 2x 2x 2x 11

880:2x 2x 2x 2x 5x 11

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 2x 2x 2x 11x 11 = 7744

Therefore, the value for common factors is 7744.

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 = 39920629760/(2x7744)

LCM = 39920629760/15488

LCM = 2577520

Thus, we can understand that the LCM of 638,404,176,880 is 2577520.
