Given numbers are 817,171,988,489

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

The LCM of 817,171,988,489 is 62324028.

Find LCM of 817,171,988,489 with Prime Factorization

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

3 x 19 x 43 x 3 x 52 x 163 = 62324028

Therefore, the lowest common multiple of 817,171,988,489 is 62324028.

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.

817 x 171 x 988 x 489 = 67496922324

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.

817 : 1, 19, 43, 817

171 : 1, 3, 9, 19, 57, 171

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,171,988,489, is 1.

Now, the common factors can be found like this.

817:19x 43

171:3x 3x 19

988:2x 2x 13x 19

489:3x 163

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 19x 19 = 1083

Therefore, the value for common factors is 1083.

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 = 67496922324/(1x1083)

LCM = 67496922324/1083

LCM = 62324028

Thus, we can understand that the LCM of 817,171,988,489 is 62324028.
