Given numbers are 731,128,338,663

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

The LCM of 731,128,338,663 is 47438976.

Find LCM of 731,128,338,663 with Prime Factorization

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

2 x 13 x 17 x 43 x 64 x 13 x 3 = 47438976

Therefore, the lowest common multiple of 731,128,338,663 is 47438976.

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 128 x 338 x 663 = 20968027392

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

128 : 1, 2, 4, 8, 16, 32, 64, 128

338 : 1, 2, 13, 26, 169, 338

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 731,128,338,663, is 1.

Now, the common factors can be found like this.

731:17x 43

128:2x 2x 2x 2x 2x 2x 2

338:2x 13x 13

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.

2x 13x 17 = 442

Therefore, the value for common factors is 442.

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 = 20968027392/(1x442)

LCM = 20968027392/442

LCM = 47438976

Thus, we can understand that the LCM of 731,128,338,663 is 47438976.
