Given numbers are 406,526,728

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

The LCM of 406,526,728 is 5552456.

Find LCM of 406,526,728 with Prime Factorization

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

2 x 7 x 29 x 263 x 52 = 5552456

Therefore, the lowest common multiple of 406,526,728 is 5552456.

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.

406 x 526 x 728 = 155468768

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

526 : 1, 2, 263, 526

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,526,728, is 2.

Now, the common factors can be found like this.

406:2x 7x 29

526:2x 263

728:2x 2x 2x 7x 13

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 155468768/(2x14)

LCM = 155468768/28

LCM = 5552456

Thus, we can understand that the LCM of 406,526,728 is 5552456.
