Given numbers are 173,21,469

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

The LCM of 173,21,469 is 243411.

Find LCM of 173,21,469 with Prime Factorization

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

7 x 173 x 3 x 67 = 243411

Therefore, the lowest common multiple of 173,21,469 is 243411.

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.

173 x 21 x 469 = 1703877

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.

173 : 1, 173

21 : 1, 3, 7, 21

469 : 1, 7, 67, 469

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,21,469, is 1.

Now, the common factors can be found like this.

173:173

21:3x 7

469:7x 67

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

7 = 7

Therefore, the value for common factors is 7.

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 = 1703877/(1x7)

LCM = 1703877/7

LCM = 243411

Thus, we can understand that the LCM of 173,21,469 is 243411.

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

• LCM of 687, 25, 108
• LCM of 919, 80, 512
