Given numbers are 556,270,542

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

The LCM of 556,270,542 is 20341260.

Find LCM of 556,270,542 with Prime Factorization

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

2 x 278 x 135 x 271 = 20341260

Therefore, the lowest common multiple of 556,270,542 is 20341260.

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.

556 x 270 x 542 = 81365040

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.

556 : 1, 2, 4, 139, 278, 556

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

542 : 1, 2, 271, 542

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,270,542, is 2.

Now, the common factors can be found like this.

556:2x 2x 139

270:2x 3x 3x 3x 5

542:2x 271

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

2 = 2

Therefore, the value for common factors is 2.

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 = 81365040/(2x2)

LCM = 81365040/4

LCM = 20341260

Thus, we can understand that the LCM of 556,270,542 is 20341260.
