Given numbers are 406,465,728,280,251

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

The LCM of 406,465,728,280,251 is 2464087080.

Find LCM of 406,465,728,280,251 with Prime Factorization

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

2 x 2 x 2 x 5 x 7 x 29 x 93 x 13 x 1 x 251 = 2464087080

Therefore, the lowest common multiple of 406,465,728,280,251 is 2464087080.

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 465 x 728 x 280 x 251 = 9659221353600

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

465 : 1, 3, 5, 15, 31, 93, 155, 465

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

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

251 : 1, 251

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,465,728,280,251, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

465:3x 5x 31

728:2x 2x 2x 7x 13

280:2x 2x 2x 5x 7

251:251

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

2x 2x 2x 2x 5x 7x 7 = 3920

Therefore, the value for common factors is 3920.

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 = 9659221353600/(1x3920)

LCM = 9659221353600/3920

LCM = 2464087080

Thus, we can understand that the LCM of 406,465,728,280,251 is 2464087080.
