Given numbers are 686,798,570,486

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

The LCM of 686,798,570,486 is 15836310.

Find LCM of 686,798,570,486 with Prime Factorization

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

2 x 3 x 7 x 19 x 49 x 1 x 5 x 81 = 15836310

Therefore, the lowest common multiple of 686,798,570,486 is 15836310.

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.

686 x 798 x 570 x 486 = 151648504560

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.

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

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,798,570,486, is 2.

Now, the common factors can be found like this.

686:2x 7x 7x 7

798:2x 3x 7x 19

570:2x 3x 5x 19

486:2x 3x 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 2x 3x 3x 7x 19 = 4788

Therefore, the value for common factors is 4788.

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 = 151648504560/(2x4788)

LCM = 151648504560/9576

LCM = 15836310

Thus, we can understand that the LCM of 686,798,570,486 is 15836310.
