Given numbers are 638,458,281

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

The LCM of 638,458,281 is 41054662.

Find LCM of 638,458,281 with Prime Factorization

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

2 x 319 x 229 x 281 = 41054662

Therefore, the lowest common multiple of 638,458,281 is 41054662.

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 458 x 281 = 82109324

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

458 : 1, 2, 229, 458

281 : 1, 281

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,458,281, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

458:2x 229

281:281

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 = 82109324/(1x2)

LCM = 82109324/2

LCM = 41054662

Thus, we can understand that the LCM of 638,458,281 is 41054662.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 500, 369, 665
• LCM of 187, 960, 970
