Given numbers are 489,355,128,162

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

The LCM of 489,355,128,162 is 599944320.

Find LCM of 489,355,128,162 with Prime Factorization

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

2 x 3 x 163 x 355 x 64 x 27 = 599944320

Therefore, the lowest common multiple of 489,355,128,162 is 599944320.

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.

489 x 355 x 128 x 162 = 3599665920

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.

489 : 1, 3, 163, 489

355 : 1, 5, 71, 355

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

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,355,128,162, is 1.

Now, the common factors can be found like this.

489:3x 163

355:5x 71

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

162:2x 3x 3x 3x 3

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 = 3599665920/(1x6)

LCM = 3599665920/6

LCM = 599944320

Thus, we can understand that the LCM of 489,355,128,162 is 599944320.
