Given numbers are 856,206,990

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

The LCM of 856,206,990 is 43643160.

Find LCM of 856,206,990 with Prime Factorization

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

2 x 428 x 103 x 495 = 43643160

Therefore, the lowest common multiple of 856,206,990 is 43643160.

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.

856 x 206 x 990 = 174572640

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

206 : 1, 2, 103, 206

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,206,990, is 2.

Now, the common factors can be found like this.

856:2x 2x 2x 107

206:2x 103

990:2x 3x 3x 5x 11

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

2 = 2

Therefore, the value for common factors is 2.

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 = 174572640/(2x2)

LCM = 174572640/4

LCM = 43643160

Thus, we can understand that the LCM of 856,206,990 is 43643160.

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

• LCM of 921, 622, 272
