Given numbers are 517,169,806,689

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

The LCM of 517,169,806,689 is 287107678.

Find LCM of 517,169,806,689 with Prime Factorization

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

13 x 517 x 13 x 62 x 53 = 287107678

Therefore, the lowest common multiple of 517,169,806,689 is 287107678.

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.

517 x 169 x 806 x 689 = 48521197582

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.

517 : 1, 11, 47, 517

169 : 1, 13, 169

806 : 1, 2, 13, 26, 31, 62, 403, 806

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,169,806,689, is 1.

Now, the common factors can be found like this.

517:11x 47

169:13x 13

806:2x 13x 31

689:13x 53

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 48521197582/(1x169)

LCM = 48521197582/169

LCM = 287107678

Thus, we can understand that the LCM of 517,169,806,689 is 287107678.
