Given numbers are 128,147,394,489

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

The LCM of 128,147,394,489 is 604200576.

Find LCM of 128,147,394,489 with Prime Factorization

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

2 x 3 x 64 x 49 x 197 x 163 = 604200576

Therefore, the lowest common multiple of 128,147,394,489 is 604200576.

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 147 x 394 x 489 = 3625203456

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

147 : 1, 3, 7, 21, 49, 147

394 : 1, 2, 197, 394

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,147,394,489, is 1.

Now, the common factors can be found like this.

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

147:3x 7x 7

394:2x 197

489:3x 163

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 3625203456/(1x6)

LCM = 3625203456/6

LCM = 604200576

Thus, we can understand that the LCM of 128,147,394,489 is 604200576.
