Given numbers are 731,171,209

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

The LCM of 731,171,209 is 1375011.

Find LCM of 731,171,209 with Prime Factorization

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

19 x 731 x 9 x 11 = 1375011

Therefore, the lowest common multiple of 731,171,209 is 1375011.

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.

731 x 171 x 209 = 26125209

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.

731 : 1, 17, 43, 731

171 : 1, 3, 9, 19, 57, 171

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,171,209, is 1.

Now, the common factors can be found like this.

731:17x 43

171:3x 3x 19

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.

19 = 19

Therefore, the value for common factors is 19.

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 = 26125209/(1x19)

LCM = 26125209/19

LCM = 1375011

Thus, we can understand that the LCM of 731,171,209 is 1375011.

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

• LCM of 667, 227, 847
• LCM of 323, 416, 967
