Given numbers are 161,725,865,409

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

The LCM of 161,725,865,409 is 8259110825.

Find LCM of 161,725,865,409 with Prime Factorization

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

5 x 161 x 145 x 173 x 409 = 8259110825

Therefore, the lowest common multiple of 161,725,865,409 is 8259110825.

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.

161 x 725 x 865 x 409 = 41295554125

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.

161 : 1, 7, 23, 161

725 : 1, 5, 25, 29, 145, 725

865 : 1, 5, 173, 865

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,725,865,409, is 1.

Now, the common factors can be found like this.

161:7x 23

725:5x 5x 29

865:5x 173

409:409

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

5 = 5

Therefore, the value for common factors is 5.

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 = 41295554125/(1x5)

LCM = 41295554125/5

LCM = 8259110825

Thus, we can understand that the LCM of 161,725,865,409 is 8259110825.
