Given numbers are 247,209,143

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

The LCM of 247,209,143 is 2717.

Find LCM of 247,209,143 with Prime Factorization

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

11 x 13 x 19 x 1 x 1 x 1 = 2717

Therefore, the lowest common multiple of 247,209,143 is 2717.

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.

247 x 209 x 143 = 7382089

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.

247 : 1, 13, 19, 247

209 : 1, 11, 19, 209

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,209,143, is 1.

Now, the common factors can be found like this.

247:13x 19

209:11x 19

143:11x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

11x 13x 19 = 2717

Therefore, the value for common factors is 2717.

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 = 7382089/(1x2717)

LCM = 7382089/2717

LCM = 2717

Thus, we can understand that the LCM of 247,209,143 is 2717.

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

• LCM of 244, 655, 608
• LCM of 739, 771, 388
