Given numbers are 513,19,731

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

The LCM of 513,19,731 is 375003.

Find LCM of 513,19,731 with Prime Factorization

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

19 x 27 x 1 x 731 = 375003

Therefore, the lowest common multiple of 513,19,731 is 375003.

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.

513 x 19 x 731 = 7125057

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.

513 : 1, 3, 9, 19, 27, 57, 171, 513

19 : 1, 19

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,19,731, is 1.

Now, the common factors can be found like this.

513:3x 3x 3x 19

19:19

731:17x 43

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 = 7125057/(1x19)

LCM = 7125057/19

LCM = 375003

Thus, we can understand that the LCM of 513,19,731 is 375003.

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

• LCM of 658, 44, 705
• LCM of 589, 70, 521
