Given numbers are 638,236,834

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

The LCM of 638,236,834 is 31393428.

Find LCM of 638,236,834 with Prime Factorization

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

2 x 319 x 118 x 417 = 31393428

Therefore, the lowest common multiple of 638,236,834 is 31393428.

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 236 x 834 = 125573712

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

236 : 1, 2, 4, 59, 118, 236

834 : 1, 2, 3, 6, 139, 278, 417, 834

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,236,834, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

236:2x 2x 59

834:2x 3x 139

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

2 = 2

Therefore, the value for common factors is 2.

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 = 125573712/(2x2)

LCM = 125573712/4

LCM = 31393428

Thus, we can understand that the LCM of 638,236,834 is 31393428.
