Given numbers are 987,283,422,290,206

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

The LCM of 987,283,422,290,206 is 1760440154970.

Find LCM of 987,283,422,290,206 with Prime Factorization

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

2 x 987 x 283 x 211 x 145 x 103 = 1760440154970

Therefore, the lowest common multiple of 987,283,422,290,206 is 1760440154970.

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.

987 x 283 x 422 x 290 x 206 = 7041760619880

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.

987 : 1, 3, 7, 21, 47, 141, 329, 987

283 : 1, 283

422 : 1, 2, 211, 422

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

206 : 1, 2, 103, 206

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,283,422,290,206, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

283:283

422:2x 211

290:2x 5x 29

206:2x 103

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 7041760619880/(1x4)

LCM = 7041760619880/4

LCM = 1760440154970

Thus, we can understand that the LCM of 987,283,422,290,206 is 1760440154970.
