Given numbers are 642,149,519

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

The LCM of 642,149,519 is 16548834.

Find LCM of 642,149,519 with Prime Factorization

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

3 x 214 x 149 x 173 = 16548834

Therefore, the lowest common multiple of 642,149,519 is 16548834.

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.

642 x 149 x 519 = 49646502

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

149 : 1, 149

519 : 1, 3, 173, 519

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,149,519, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

149:149

519:3x 173

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

3 = 3

Therefore, the value for common factors is 3.

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 = 49646502/(1x3)

LCM = 49646502/3

LCM = 16548834

Thus, we can understand that the LCM of 642,149,519 is 16548834.

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

• LCM of 104, 762, 895
• LCM of 915, 376, 457
