Given numbers are 815,705,521

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

The LCM of 815,705,521 is 59870715.

Find LCM of 815,705,521 with Prime Factorization

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

5 x 163 x 141 x 521 = 59870715

Therefore, the lowest common multiple of 815,705,521 is 59870715.

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.

815 x 705 x 521 = 299353575

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.

815 : 1, 5, 163, 815

705 : 1, 3, 5, 15, 47, 141, 235, 705

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,705,521, is 1.

Now, the common factors can be found like this.

815:5x 163

705:3x 5x 47

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 = 299353575/(1x5)

LCM = 299353575/5

LCM = 59870715

Thus, we can understand that the LCM of 815,705,521 is 59870715.

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

• LCM of 437, 114, 311
• LCM of 581, 569, 697
