Given numbers are 395,161,219,409,391

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

The LCM of 395,161,219,409,391 is 96836551665.

Find LCM of 395,161,219,409,391 with Prime Factorization

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

23 x 395 x 7 x 219 x 409 x 17 = 96836551665

Therefore, the lowest common multiple of 395,161,219,409,391 is 96836551665.

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.

395 x 161 x 219 x 409 x 391 = 2227240688295

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.

395 : 1, 5, 79, 395

161 : 1, 7, 23, 161

219 : 1, 3, 73, 219

409 : 1, 409

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,161,219,409,391, is 1.

Now, the common factors can be found like this.

395:5x 79

161:7x 23

219:3x 73

409:409

391:17x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 2227240688295/(1x23)

LCM = 2227240688295/23

LCM = 96836551665

Thus, we can understand that the LCM of 395,161,219,409,391 is 96836551665.
