Given numbers are 818,247,423,208

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

The LCM of 818,247,423,208 is 683723664.

Find LCM of 818,247,423,208 with Prime Factorization

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

2 x 13 x 409 x 19 x 423 x 8 = 683723664

Therefore, the lowest common multiple of 818,247,423,208 is 683723664.

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.

818 x 247 x 423 x 208 = 17776815264

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.

818 : 1, 2, 409, 818

247 : 1, 13, 19, 247

423 : 1, 3, 9, 47, 141, 423

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,247,423,208, is 1.

Now, the common factors can be found like this.

818:2x 409

247:13x 19

423:3x 3x 47

208:2x 2x 2x 2x 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 13 = 26

Therefore, the value for common factors is 26.

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 = 17776815264/(1x26)

LCM = 17776815264/26

LCM = 683723664

Thus, we can understand that the LCM of 818,247,423,208 is 683723664.
