Given numbers are 126,129,431

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

The LCM of 126,129,431 is 2335158.

Find LCM of 126,129,431 with Prime Factorization

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

3 x 42 x 43 x 431 = 2335158

Therefore, the lowest common multiple of 126,129,431 is 2335158.

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.

126 x 129 x 431 = 7005474

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.

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

129 : 1, 3, 43, 129

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,129,431, is 1.

Now, the common factors can be found like this.

126:2x 3x 3x 7

129:3x 43

431:431

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 = 7005474/(1x3)

LCM = 7005474/3

LCM = 2335158

Thus, we can understand that the LCM of 126,129,431 is 2335158.

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

• LCM of 667, 757, 138
• LCM of 196, 708, 712
• LCM of 703, 900, 109
