Given numbers are 489,770,517,521

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

The LCM of 489,770,517,521 is 9220090110.

Find LCM of 489,770,517,521 with Prime Factorization

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

11 x 489 x 70 x 47 x 521 = 9220090110

Therefore, the lowest common multiple of 489,770,517,521 is 9220090110.

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 770 x 517 x 521 = 101420991210

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

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

517 : 1, 11, 47, 517

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,770,517,521, is 1.

Now, the common factors can be found like this.

489:3x 163

770:2x 5x 7x 11

517:11x 47

521:521

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

11 = 11

Therefore, the value for common factors is 11.

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 = 101420991210/(1x11)

LCM = 101420991210/11

LCM = 9220090110

Thus, we can understand that the LCM of 489,770,517,521 is 9220090110.
