Given numbers are 138,63,129

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

The LCM of 138,63,129 is 124614.

Find LCM of 138,63,129 with Prime Factorization

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

3 x 46 x 21 x 43 = 124614

Therefore, the lowest common multiple of 138,63,129 is 124614.

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.

138 x 63 x 129 = 1121526

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

63 : 1, 3, 7, 9, 21, 63

129 : 1, 3, 43, 129

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,63,129, is 3.

Now, the common factors can be found like this.

138:2x 3x 23

63:3x 3x 7

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 = 1121526/(3x3)

LCM = 1121526/9

LCM = 124614

Thus, we can understand that the LCM of 138,63,129 is 124614.

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

• LCM of 168, 83, 114
• LCM of 220, 56, 949
