Given numbers are 423,478,129

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

The LCM of 423,478,129 is 8694342.

Find LCM of 423,478,129 with Prime Factorization

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

3 x 141 x 478 x 43 = 8694342

Therefore, the lowest common multiple of 423,478,129 is 8694342.

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.

423 x 478 x 129 = 26083026

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.

423 : 1, 3, 9, 47, 141, 423

478 : 1, 2, 239, 478

129 : 1, 3, 43, 129

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,478,129, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

478:2x 239

129:3x 43

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 = 26083026/(1x3)

LCM = 26083026/3

LCM = 8694342

Thus, we can understand that the LCM of 423,478,129 is 8694342.

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

• LCM of 468, 657, 960
• LCM of 206, 442, 150
