Given numbers are 128,323,740

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

The LCM of 128,323,740 is 7648640.

Find LCM of 128,323,740 with Prime Factorization

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

2 x 2 x 32 x 323 x 185 = 7648640

Therefore, the lowest common multiple of 128,323,740 is 7648640.

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 323 x 740 = 30594560

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

323 : 1, 17, 19, 323

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,323,740, is 1.

Now, the common factors can be found like this.

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

323:17x 19

740:2x 2x 5x 37

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 30594560/(1x4)

LCM = 30594560/4

LCM = 7648640

Thus, we can understand that the LCM of 128,323,740 is 7648640.
