Given numbers are 290,286,247,487

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

The LCM of 290,286,247,487 is 383721910.

Find LCM of 290,286,247,487 with Prime Factorization

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

2 x 13 x 145 x 11 x 19 x 487 = 383721910

Therefore, the lowest common multiple of 290,286,247,487 is 383721910.

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.

290 x 286 x 247 x 487 = 9976769660

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.

290 : 1, 2, 5, 10, 29, 58, 145, 290

286 : 1, 2, 11, 13, 22, 26, 143, 286

247 : 1, 13, 19, 247

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,286,247,487, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

286:2x 11x 13

247:13x 19

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 13 = 26

Therefore, the value for common factors is 26.

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 = 9976769660/(1x26)

LCM = 9976769660/26

LCM = 383721910

Thus, we can understand that the LCM of 290,286,247,487 is 383721910.
