Given numbers are 406,784,272,128,884

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

The LCM of 406,784,272,128,884 is 40197248.

Find LCM of 406,784,272,128,884 with Prime Factorization

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

2 x 2 x 2 x 2 x 7 x 17 x 29 x 7 x 1 x 8 x 13 = 40197248

Therefore, the lowest common multiple of 406,784,272,128,884 is 40197248.

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 784 x 272 x 128 x 884 = 9796551704576

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

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

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

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,784,272,128,884, is 2.

Now, the common factors can be found like this.

406:2x 7x 29

784:2x 2x 2x 2x 7x 7

272:2x 2x 2x 2x 17

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

884:2x 2x 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 2x 2x 2x 2x 2x 2x 2x 2x 2x 7x 17 = 121856

Therefore, the value for common factors is 121856.

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 = 9796551704576/(2x121856)

LCM = 9796551704576/243712

LCM = 40197248

Thus, we can understand that the LCM of 406,784,272,128,884 is 40197248.
