Given numbers are 815,213,923

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

The LCM of 815,213,923 is 2256735.

Find LCM of 815,213,923 with Prime Factorization

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

71 x 815 x 3 x 13 = 2256735

Therefore, the lowest common multiple of 815,213,923 is 2256735.

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 213 x 923 = 160228185

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

213 : 1, 3, 71, 213

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,213,923, is 1.

Now, the common factors can be found like this.

815:5x 163

213:3x 71

923:13x 71

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

71 = 71

Therefore, the value for common factors is 71.

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 = 160228185/(1x71)

LCM = 160228185/71

LCM = 2256735

Thus, we can understand that the LCM of 815,213,923 is 2256735.

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

• LCM of 514, 910, 437
• LCM of 997, 317, 180
