Given numbers are 287,255,198,391

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

The LCM of 287,255,198,391 is 111094830.

Find LCM of 287,255,198,391 with Prime Factorization

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

3 x 17 x 287 x 5 x 66 x 23 = 111094830

Therefore, the lowest common multiple of 287,255,198,391 is 111094830.

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.

287 x 255 x 198 x 391 = 5665836330

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.

287 : 1, 7, 41, 287

255 : 1, 3, 5, 15, 17, 51, 85, 255

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,255,198,391, is 1.

Now, the common factors can be found like this.

287:7x 41

255:3x 5x 17

198:2x 3x 3x 11

391:17x 23

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

3x 17 = 51

Therefore, the value for common factors is 51.

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 = 5665836330/(1x51)

LCM = 5665836330/51

LCM = 111094830

Thus, we can understand that the LCM of 287,255,198,391 is 111094830.
