Given numbers are 399,409,843

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

The LCM of 399,409,843 is 45856671.

Find LCM of 399,409,843 with Prime Factorization

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

3 x 133 x 409 x 281 = 45856671

Therefore, the lowest common multiple of 399,409,843 is 45856671.

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 409 x 843 = 137570013

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

409 : 1, 409

843 : 1, 3, 281, 843

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,409,843, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

409:409

843:3x 281

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 = 137570013/(1x3)

LCM = 137570013/3

LCM = 45856671

Thus, we can understand that the LCM of 399,409,843 is 45856671.

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

• LCM of 614, 911, 930
• LCM of 906, 561, 527
• LCM of 517, 268, 174
