Given numbers are 487,168,138,579

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

The LCM of 487,168,138,579 is 363181224.

Find LCM of 487,168,138,579 with Prime Factorization

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

2 x 3 x 487 x 28 x 23 x 193 = 363181224

Therefore, the lowest common multiple of 487,168,138,579 is 363181224.

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.

487 x 168 x 138 x 579 = 6537262032

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.

487 : 1, 487

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

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

579 : 1, 3, 193, 579

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,168,138,579, is 1.

Now, the common factors can be found like this.

487:487

168:2x 2x 2x 3x 7

138:2x 3x 23

579:3x 193

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 3 = 18

Therefore, the value for common factors is 18.

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 = 6537262032/(1x18)

LCM = 6537262032/18

LCM = 363181224

Thus, we can understand that the LCM of 487,168,138,579 is 363181224.
