Given numbers are 393,781,143

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

The LCM of 393,781,143 is 3990129.

Find LCM of 393,781,143 with Prime Factorization

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

11 x 393 x 71 x 13 = 3990129

Therefore, the lowest common multiple of 393,781,143 is 3990129.

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.

393 x 781 x 143 = 43891419

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.

393 : 1, 3, 131, 393

781 : 1, 11, 71, 781

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,781,143, is 1.

Now, the common factors can be found like this.

393:3x 131

781:11x 71

143:11x 13

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

11 = 11

Therefore, the value for common factors is 11.

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 = 43891419/(1x11)

LCM = 43891419/11

LCM = 3990129

Thus, we can understand that the LCM of 393,781,143 is 3990129.

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

• LCM of 694, 145, 508
• LCM of 461, 656, 324
