Given numbers are 199,256,128,891

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

The LCM of 199,256,128,891 is 45391104.

Find LCM of 199,256,128,891 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 2 x 199 x 1 x 2 x 891 = 45391104

Therefore, the lowest common multiple of 199,256,128,891 is 45391104.

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 256 x 128 x 891 = 5810061312

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

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

128 : 1, 2, 4, 8, 16, 32, 64, 128

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,256,128,891, is 1.

Now, the common factors can be found like this.

199:199

256:2x 2x 2x 2x 2x 2x 2x 2

128:2x 2x 2x 2x 2x 2x 2

891:3x 3x 3x 3x 11

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

2x 2x 2x 2x 2x 2x 2 = 128

Therefore, the value for common factors is 128.

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 = 5810061312/(1x128)

LCM = 5810061312/128

LCM = 45391104

Thus, we can understand that the LCM of 199,256,128,891 is 45391104.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 439, 719, 320, 325
