Given numbers are 171,538,687

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

The LCM of 171,538,687 is 21067542.

Find LCM of 171,538,687 with Prime Factorization

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

3 x 57 x 538 x 229 = 21067542

Therefore, the lowest common multiple of 171,538,687 is 21067542.

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.

171 x 538 x 687 = 63202626

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.

171 : 1, 3, 9, 19, 57, 171

538 : 1, 2, 269, 538

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,538,687, is 1.

Now, the common factors can be found like this.

171:3x 3x 19

538:2x 269

687:3x 229

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 = 63202626/(1x3)

LCM = 63202626/3

LCM = 21067542

Thus, we can understand that the LCM of 171,538,687 is 21067542.

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

• LCM of 679, 930, 347
• LCM of 687, 660, 700
