Given numbers are 399,879,409

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

The LCM of 399,879,409 is 47814963.

Find LCM of 399,879,409 with Prime Factorization

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

3 x 133 x 293 x 409 = 47814963

Therefore, the lowest common multiple of 399,879,409 is 47814963.

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.

399 x 879 x 409 = 143444889

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

879 : 1, 3, 293, 879

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,879,409, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

879:3x 293

409:409

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 = 143444889/(1x3)

LCM = 143444889/3

LCM = 47814963

Thus, we can understand that the LCM of 399,879,409 is 47814963.

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

• LCM of 426, 845, 516
• LCM of 971, 303, 350
• LCM of 508, 203, 802
