Given numbers are 199,381,286,646

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

The LCM of 199,381,286,646 is 7004007582.

Find LCM of 199,381,286,646 with Prime Factorization

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

2 x 199 x 381 x 143 x 323 = 7004007582

Therefore, the lowest common multiple of 199,381,286,646 is 7004007582.

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.

199 x 381 x 286 x 646 = 14008015164

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.

199 : 1, 199

381 : 1, 3, 127, 381

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,381,286,646, is 1.

Now, the common factors can be found like this.

199:199

381:3x 127

286:2x 11x 13

646:2x 17x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 14008015164/(1x2)

LCM = 14008015164/2

LCM = 7004007582

Thus, we can understand that the LCM of 199,381,286,646 is 7004007582.
