Given numbers are 368,621,138,171

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

The LCM of 368,621,138,171 is 188784.

Find LCM of 368,621,138,171 with Prime Factorization

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

2 x 3 x 3 x 23 x 8 x 3 x 1 x 19 = 188784

Therefore, the lowest common multiple of 368,621,138,171 is 188784.

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.

368 x 621 x 138 x 171 = 5392803744

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.

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

621 : 1, 3, 9, 23, 27, 69, 207, 621

138 : 1, 2, 3, 6, 23, 46, 69, 138

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,621,138,171, is 1.

Now, the common factors can be found like this.

368:2x 2x 2x 2x 23

621:3x 3x 3x 23

138:2x 3x 23

171:3x 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.

2x 3x 3x 3x 23x 23 = 28566

Therefore, the value for common factors is 28566.

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 = 5392803744/(1x28566)

LCM = 5392803744/28566

LCM = 188784

Thus, we can understand that the LCM of 368,621,138,171 is 188784.
