Given numbers are 3,128,173,290

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

The LCM of 3,128,173,290 is 9632640.

Find LCM of 3,128,173,290 with Prime Factorization

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

2 x 3 x 64 x 173 x 145 = 9632640

Therefore, the lowest common multiple of 3,128,173,290 is 9632640.

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.

3 x 128 x 173 x 290 = 19265280

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.

3 : 1, 3

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

173 : 1, 173

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,128,173,290, is 1.

Now, the common factors can be found like this.

3:3

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

173:173

290:2x 5x 29

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 = 19265280/(1x2)

LCM = 19265280/2

LCM = 9632640

Thus, we can understand that the LCM of 3,128,173,290 is 9632640.
