Given numbers are 685,247,458,214

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

The LCM of 685,247,458,214 is 8291570170.

Find LCM of 685,247,458,214 with Prime Factorization

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

2 x 685 x 247 x 229 x 107 = 8291570170

Therefore, the lowest common multiple of 685,247,458,214 is 8291570170.

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.

685 x 247 x 458 x 214 = 16583140340

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.

685 : 1, 5, 137, 685

247 : 1, 13, 19, 247

458 : 1, 2, 229, 458

214 : 1, 2, 107, 214

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,247,458,214, is 1.

Now, the common factors can be found like this.

685:5x 137

247:13x 19

458:2x 229

214:2x 107

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 = 16583140340/(1x2)

LCM = 16583140340/2

LCM = 8291570170

Thus, we can understand that the LCM of 685,247,458,214 is 8291570170.
