Given numbers are 686,471,278,766

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

The LCM of 686,471,278,766 is 17201194122.

Find LCM of 686,471,278,766 with Prime Factorization

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

2 x 343 x 471 x 139 x 383 = 17201194122

Therefore, the lowest common multiple of 686,471,278,766 is 17201194122.

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 471 x 278 x 766 = 68804776488

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

471 : 1, 3, 157, 471

278 : 1, 2, 139, 278

766 : 1, 2, 383, 766

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,471,278,766, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

471:3x 157

278:2x 139

766:2x 383

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 68804776488/(1x4)

LCM = 68804776488/4

LCM = 17201194122

Thus, we can understand that the LCM of 686,471,278,766 is 17201194122.
