Given numbers are 431,286,209

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

The LCM of 431,286,209 is 2342054.

Find LCM of 431,286,209 with Prime Factorization

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

11 x 431 x 26 x 19 = 2342054

Therefore, the lowest common multiple of 431,286,209 is 2342054.

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.

431 x 286 x 209 = 25762594

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.

431 : 1, 431

286 : 1, 2, 11, 13, 22, 26, 143, 286

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,286,209, is 1.

Now, the common factors can be found like this.

431:431

286:2x 11x 13

209:11x 19

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 = 25762594/(1x11)

LCM = 25762594/11

LCM = 2342054

Thus, we can understand that the LCM of 431,286,209 is 2342054.

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

• LCM of 222, 992, 868
• LCM of 343, 275, 176
