Given numbers are 686,471,914,524

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

The LCM of 686,471,914,524 is 38686773804.

Find LCM of 686,471,914,524 with Prime Factorization

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

2 x 343 x 471 x 457 x 262 = 38686773804

Therefore, the lowest common multiple of 686,471,914,524 is 38686773804.

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 914 x 524 = 154747095216

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

914 : 1, 2, 457, 914

524 : 1, 2, 4, 131, 262, 524

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,471,914,524, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

471:3x 157

914:2x 457

524:2x 2x 131

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 = 154747095216/(1x4)

LCM = 154747095216/4

LCM = 38686773804

Thus, we can understand that the LCM of 686,471,914,524 is 38686773804.
