Given numbers are 128,176,344,919

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

The LCM of 128,176,344,919 is 55639936.

Find LCM of 128,176,344,919 with Prime Factorization

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

2 x 2 x 2 x 2 x 8 x 11 x 43 x 919 = 55639936

Therefore, the lowest common multiple of 128,176,344,919 is 55639936.

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.

128 x 176 x 344 x 919 = 7121911808

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.

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

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

344 : 1, 2, 4, 8, 43, 86, 172, 344

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,176,344,919, is 1.

Now, the common factors can be found like this.

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

176:2x 2x 2x 2x 11

344:2x 2x 2x 43

919:919

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 = 7121911808/(1x128)

LCM = 7121911808/128

LCM = 55639936

Thus, we can understand that the LCM of 128,176,344,919 is 55639936.
