Given numbers are 409,361,917,393

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

The LCM of 409,361,917,393 is 406182399.

Find LCM of 409,361,917,393 with Prime Factorization

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

131 x 409 x 361 x 7 x 3 = 406182399

Therefore, the lowest common multiple of 409,361,917,393 is 406182399.

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.

409 x 361 x 917 x 393 = 53209894269

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.

409 : 1, 409

361 : 1, 19, 361

917 : 1, 7, 131, 917

393 : 1, 3, 131, 393

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,361,917,393, is 1.

Now, the common factors can be found like this.

409:409

361:19x 19

917:7x 131

393:3x 131

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

131 = 131

Therefore, the value for common factors is 131.

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 = 53209894269/(1x131)

LCM = 53209894269/131

LCM = 406182399

Thus, we can understand that the LCM of 409,361,917,393 is 406182399.
