Given numbers are 865,309,721

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

The LCM of 865,309,721 is 1870995.

Find LCM of 865,309,721 with Prime Factorization

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

103 x 865 x 3 x 7 = 1870995

Therefore, the lowest common multiple of 865,309,721 is 1870995.

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 309 x 721 = 192712485

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

309 : 1, 3, 103, 309

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,309,721, is 1.

Now, the common factors can be found like this.

865:5x 173

309:3x 103

721:7x 103

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

103 = 103

Therefore, the value for common factors is 103.

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 = 192712485/(1x103)

LCM = 192712485/103

LCM = 1870995

Thus, we can understand that the LCM of 865,309,721 is 1870995.

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

• LCM of 110, 583, 310
• LCM of 135, 301, 171
