Given numbers are 731,553,215

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

The LCM of 731,553,215 is 2021215.

Find LCM of 731,553,215 with Prime Factorization

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

43 x 17 x 553 x 5 = 2021215

Therefore, the lowest common multiple of 731,553,215 is 2021215.

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 553 x 215 = 86912245

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

553 : 1, 7, 79, 553

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,553,215, is 1.

Now, the common factors can be found like this.

731:17x 43

553:7x 79

215:5x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 86912245/(1x43)

LCM = 86912245/43

LCM = 2021215

Thus, we can understand that the LCM of 731,553,215 is 2021215.

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

• LCM of 425, 884, 489
