Given numbers are 487,204,170,847

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

The LCM of 487,204,170,847 is 420738780.

Find LCM of 487,204,170,847 with Prime Factorization

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

2 x 17 x 487 x 6 x 5 x 847 = 420738780

Therefore, the lowest common multiple of 487,204,170,847 is 420738780.

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 204 x 170 x 847 = 14305118520

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

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

170 : 1, 2, 5, 10, 17, 34, 85, 170

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,204,170,847, is 1.

Now, the common factors can be found like this.

487:487

204:2x 2x 3x 17

170:2x 5x 17

847:7x 11x 11

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 14305118520/(1x34)

LCM = 14305118520/34

LCM = 420738780

Thus, we can understand that the LCM of 487,204,170,847 is 420738780.
