Given numbers are 656,686,135,523

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

The LCM of 656,686,135,523 is 15886689840.

Find LCM of 656,686,135,523 with Prime Factorization

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

2 x 328 x 343 x 135 x 523 = 15886689840

Therefore, the lowest common multiple of 656,686,135,523 is 15886689840.

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.

656 x 686 x 135 x 523 = 31773379680

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.

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

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

135 : 1, 3, 5, 9, 15, 27, 45, 135

523 : 1, 523

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,686,135,523, is 1.

Now, the common factors can be found like this.

656:2x 2x 2x 2x 41

686:2x 7x 7x 7

135:3x 3x 3x 5

523:523

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 = 31773379680/(1x2)

LCM = 31773379680/2

LCM = 15886689840

Thus, we can understand that the LCM of 656,686,135,523 is 15886689840.
