Given numbers are 489,489,393,434

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

The LCM of 489,489,393,434 is 27801606.

Find LCM of 489,489,393,434 with Prime Factorization

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

3 x 163 x 1 x 1 x 131 x 434 = 27801606

Therefore, the lowest common multiple of 489,489,393,434 is 27801606.

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 489 x 393 x 434 = 40784956002

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

489 : 1, 3, 163, 489

393 : 1, 3, 131, 393

434 : 1, 2, 7, 14, 31, 62, 217, 434

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,489,393,434, is 1.

Now, the common factors can be found like this.

489:3x 163

489:3x 163

393:3x 131

434:2x 7x 31

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

3x 3x 163 = 1467

Therefore, the value for common factors is 1467.

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 = 40784956002/(1x1467)

LCM = 40784956002/1467

LCM = 27801606

Thus, we can understand that the LCM of 489,489,393,434 is 27801606.
