Calculate the LCM of 171,663,331,684

Given numbers are 171,663,331,684

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

The LCM of 171,663,331,684 is 50035284.

Find LCM of 171,663,331,684 with Prime Factorization


3 171, 663, 331, 684
3 57, 221, 331, 228
19 19, 221, 331, 76
1, 221, 331, 4

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

3 x 3 x 19 x 1 x 221 x 331 x 4 = 50035284

Therefore, the lowest common multiple of 171,663,331,684 is 50035284.

LCM Formula to Find Lowest Common Multiple of 171,663,331,684

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.

171 x 663 x 331 x 684 = 25668100692

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.

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

663 : 1, 3, 13, 17, 39, 51, 221, 663

331 : 1, 331

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,663,331,684, is 1.

Now, the common factors can be found like this.

171:3x 3x 19

663:3x 13x 17

331:331

684:2x 2x 3x 3x 19

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

3x 3x 3x 19 = 513

Therefore, the value for common factors is 513.

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 = 25668100692/(1x513)

LCM = 25668100692/513

LCM = 50035284

Thus, we can understand that the LCM of 171,663,331,684 is 50035284.
