Given numbers are 865,605,521

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

The LCM of 865,605,521 is 54530465.

Find LCM of 865,605,521 with Prime Factorization

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

5 x 173 x 121 x 521 = 54530465

Therefore, the lowest common multiple of 865,605,521 is 54530465.

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.

865 x 605 x 521 = 272652325

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.

865 : 1, 5, 173, 865

605 : 1, 5, 11, 55, 121, 605

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,605,521, is 1.

Now, the common factors can be found like this.

865:5x 173

605:5x 11x 11

521:521

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

5 = 5

Therefore, the value for common factors is 5.

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 = 272652325/(1x5)

LCM = 272652325/5

LCM = 54530465

Thus, we can understand that the LCM of 865,605,521 is 54530465.

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

• LCM of 214, 348, 845
• LCM of 145, 358, 148
• LCM of 972, 419, 383
