Given numbers are 398,538,817,880,891

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

The LCM of 398,538,817,880,891 is 3117418468560.

Find LCM of 398,538,817,880,891 with Prime Factorization

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

2 x 11 x 199 x 269 x 817 x 40 x 81 = 3117418468560

Therefore, the lowest common multiple of 398,538,817,880,891 is 3117418468560.

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 538 x 817 x 880 x 891 = 137166412616640

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

538 : 1, 2, 269, 538

817 : 1, 19, 43, 817

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,538,817,880,891, is 1.

Now, the common factors can be found like this.

398:2x 199

538:2x 269

817:19x 43

880:2x 2x 2x 2x 5x 11

891:3x 3x 3x 3x 11

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 11 = 44

Therefore, the value for common factors is 44.

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 = 137166412616640/(1x44)

LCM = 137166412616640/44

LCM = 3117418468560

Thus, we can understand that the LCM of 398,538,817,880,891 is 3117418468560.
