Given numbers are 731,409,391

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

The LCM of 731,409,391 is 6876517.

Find LCM of 731,409,391 with Prime Factorization

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

17 x 43 x 409 x 23 = 6876517

Therefore, the lowest common multiple of 731,409,391 is 6876517.

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 409 x 391 = 116900789

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

409 : 1, 409

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,409,391, is 1.

Now, the common factors can be found like this.

731:17x 43

409:409

391:17x 23

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

17 = 17

Therefore, the value for common factors is 17.

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 = 116900789/(1x17)

LCM = 116900789/17

LCM = 6876517

Thus, we can understand that the LCM of 731,409,391 is 6876517.

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

• LCM of 982, 716, 292
