Given numbers are 258,492,784,408

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

The LCM of 258,492,784,408 is 70491792.

Find LCM of 258,492,784,408 with Prime Factorization

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

2 x 2 x 2 x 3 x 43 x 41 x 98 x 17 = 70491792

Therefore, the lowest common multiple of 258,492,784,408 is 70491792.

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.

258 x 492 x 784 x 408 = 40603272192

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.

258 : 1, 2, 3, 6, 43, 86, 129, 258

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

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

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,492,784,408, is 2.

Now, the common factors can be found like this.

258:2x 3x 43

492:2x 2x 3x 41

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

408:2x 2x 2x 3x 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 3x 3 = 288

Therefore, the value for common factors is 288.

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 = 40603272192/(2x288)

LCM = 40603272192/576

LCM = 70491792

Thus, we can understand that the LCM of 258,492,784,408 is 70491792.
