Given numbers are 517,170,921,686

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

The LCM of 517,170,921,686 is 27764714670.

Find LCM of 517,170,921,686 with Prime Factorization

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

2 x 517 x 85 x 921 x 343 = 27764714670

Therefore, the lowest common multiple of 517,170,921,686 is 27764714670.

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 170 x 921 x 686 = 55529429340

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

170 : 1, 2, 5, 10, 17, 34, 85, 170

921 : 1, 3, 307, 921

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,170,921,686, is 1.

Now, the common factors can be found like this.

517:11x 47

170:2x 5x 17

921:3x 307

686:2x 7x 7x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 55529429340/(1x2)

LCM = 55529429340/2

LCM = 27764714670

Thus, we can understand that the LCM of 517,170,921,686 is 27764714670.
