Given numbers are 249,867,821

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

The LCM of 249,867,821 is 59079981.

Find LCM of 249,867,821 with Prime Factorization

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

3 x 83 x 289 x 821 = 59079981

Therefore, the lowest common multiple of 249,867,821 is 59079981.

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.

249 x 867 x 821 = 177239943

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.

249 : 1, 3, 83, 249

867 : 1, 3, 17, 51, 289, 867

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,867,821, is 1.

Now, the common factors can be found like this.

249:3x 83

867:3x 17x 17

821:821

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 = 177239943/(1x3)

LCM = 177239943/3

LCM = 59079981

Thus, we can understand that the LCM of 249,867,821 is 59079981.

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

• LCM of 504, 295, 914
• LCM of 560, 237, 418
