Given numbers are 731,461,289,663

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

The LCM of 731,461,289,663 is 223425033.

Find LCM of 731,461,289,663 with Prime Factorization

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

17 x 43 x 461 x 17 x 39 = 223425033

Therefore, the lowest common multiple of 731,461,289,663 is 223425033.

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 461 x 289 x 663 = 64569834537

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

461 : 1, 461

289 : 1, 17, 289

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,461,289,663, is 1.

Now, the common factors can be found like this.

731:17x 43

461:461

289:17x 17

663:3x 13x 17

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

17x 17 = 289

Therefore, the value for common factors is 289.

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 = 64569834537/(1x289)

LCM = 64569834537/289

LCM = 223425033

Thus, we can understand that the LCM of 731,461,289,663 is 223425033.
