Given numbers are 247,313,664,689,819

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

The LCM of 247,313,664,689,819 is 171405908856.

Find LCM of 247,313,664,689,819 with Prime Factorization

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

13 x 19 x 313 x 664 x 53 x 63 = 171405908856

Therefore, the lowest common multiple of 247,313,664,689,819 is 171405908856.

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.

247 x 313 x 664 x 689 x 819 = 28967598596664

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.

247 : 1, 13, 19, 247

313 : 1, 313

664 : 1, 2, 4, 8, 83, 166, 332, 664

689 : 1, 13, 53, 689

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,313,664,689,819, is 1.

Now, the common factors can be found like this.

247:13x 19

313:313

664:2x 2x 2x 83

689:13x 53

819:3x 3x 7x 13

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 28967598596664/(1x169)

LCM = 28967598596664/169

LCM = 171405908856

Thus, we can understand that the LCM of 247,313,664,689,819 is 171405908856.
