Given numbers are 849,87,865

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

The LCM of 849,87,865 is 21297165.

Find LCM of 849,87,865 with Prime Factorization

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

3 x 283 x 29 x 865 = 21297165

Therefore, the lowest common multiple of 849,87,865 is 21297165.

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.

849 x 87 x 865 = 63891495

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.

849 : 1, 3, 283, 849

87 : 1, 3, 29, 87

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 849,87,865, is 1.

Now, the common factors can be found like this.

849:3x 283

87:3x 29

865:5x 173

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

3 = 3

Therefore, the value for common factors is 3.

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 = 63891495/(1x3)

LCM = 63891495/3

LCM = 21297165

Thus, we can understand that the LCM of 849,87,865 is 21297165.

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

• LCM of 880, 38, 468
• LCM of 335, 10, 693
