Given numbers are 398,684,168,272,711

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

The LCM of 398,684,168,272,711 is 5118506064.

Find LCM of 398,684,168,272,711 with Prime Factorization

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

2 x 2 x 2 x 3 x 3 x 199 x 19 x 7 x 34 x 79 = 5118506064

Therefore, the lowest common multiple of 398,684,168,272,711 is 5118506064.

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.

398 x 684 x 168 x 272 x 711 = 8844778478592

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.

398 : 1, 2, 199, 398

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

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

711 : 1, 3, 9, 79, 237, 711

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,684,168,272,711, is 1.

Now, the common factors can be found like this.

398:2x 199

684:2x 2x 3x 3x 19

168:2x 2x 2x 3x 7

272:2x 2x 2x 2x 17

711:3x 3x 79

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 3x 3x 3 = 1728

Therefore, the value for common factors is 1728.

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 = 8844778478592/(1x1728)

LCM = 8844778478592/1728

LCM = 5118506064

Thus, we can understand that the LCM of 398,684,168,272,711 is 5118506064.
