Given numbers are 285,488,490,487

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

The LCM of 285,488,490,487 is 3318866040.

Find LCM of 285,488,490,487 with Prime Factorization

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

2 x 5 x 57 x 244 x 49 x 487 = 3318866040

Therefore, the lowest common multiple of 285,488,490,487 is 3318866040.

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.

285 x 488 x 490 x 487 = 33188660400

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.

285 : 1, 3, 5, 15, 19, 57, 95, 285

488 : 1, 2, 4, 8, 61, 122, 244, 488

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,488,490,487, is 1.

Now, the common factors can be found like this.

285:3x 5x 19

488:2x 2x 2x 61

490:2x 5x 7x 7

487:487

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 33188660400/(1x10)

LCM = 33188660400/10

LCM = 3318866040

Thus, we can understand that the LCM of 285,488,490,487 is 3318866040.
