Given numbers are 261,873,521,279,780

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

The LCM of 261,873,521,279,780 is 106312665420.

Find LCM of 261,873,521,279,780 with Prime Factorization

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

3 x 3 x 29 x 97 x 521 x 31 x 260 = 106312665420

Therefore, the lowest common multiple of 261,873,521,279,780 is 106312665420.

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.

261 x 873 x 521 x 279 x 780 = 25833977697060

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.

261 : 1, 3, 9, 29, 87, 261

873 : 1, 3, 9, 97, 291, 873

521 : 1, 521

279 : 1, 3, 9, 31, 93, 279

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,873,521,279,780, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

873:3x 3x 97

521:521

279:3x 3x 31

780:2x 2x 3x 5x 13

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

3x 3x 3x 3x 3 = 243

Therefore, the value for common factors is 243.

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 = 25833977697060/(1x243)

LCM = 25833977697060/243

LCM = 106312665420

Thus, we can understand that the LCM of 261,873,521,279,780 is 106312665420.
