Given numbers are 856,686,685,353

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

The LCM of 856,686,685,353 is 70995882440.

Find LCM of 856,686,685,353 with Prime Factorization

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

2 x 428 x 343 x 685 x 353 = 70995882440

Therefore, the lowest common multiple of 856,686,685,353 is 70995882440.

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.

856 x 686 x 685 x 353 = 141991764880

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

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

685 : 1, 5, 137, 685

353 : 1, 353

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,686,685,353, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

686:2x 7x 7x 7

685:5x 137

353:353

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 = 141991764880/(1x2)

LCM = 141991764880/2

LCM = 70995882440

Thus, we can understand that the LCM of 856,686,685,353 is 70995882440.
