Given numbers are 129,457,678

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

The LCM of 129,457,678 is 13323378.

Find LCM of 129,457,678 with Prime Factorization

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

3 x 43 x 457 x 226 = 13323378

Therefore, the lowest common multiple of 129,457,678 is 13323378.

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.

129 x 457 x 678 = 39970134

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.

129 : 1, 3, 43, 129

457 : 1, 457

678 : 1, 2, 3, 6, 113, 226, 339, 678

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,457,678, is 1.

Now, the common factors can be found like this.

129:3x 43

457:457

678:2x 3x 113

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 = 39970134/(1x3)

LCM = 39970134/3

LCM = 13323378

Thus, we can understand that the LCM of 129,457,678 is 13323378.

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

• LCM of 891, 221, 154
• LCM of 325, 938, 483
