Given numbers are 213,161,999,407

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

The LCM of 213,161,999,407 is 125615259.

Find LCM of 213,161,999,407 with Prime Factorization

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

3 x 37 x 71 x 161 x 9 x 11 = 125615259

Therefore, the lowest common multiple of 213,161,999,407 is 125615259.

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.

213 x 161 x 999 x 407 = 13943293749

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.

213 : 1, 3, 71, 213

161 : 1, 7, 23, 161

999 : 1, 3, 9, 27, 37, 111, 333, 999

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,161,999,407, is 1.

Now, the common factors can be found like this.

213:3x 71

161:7x 23

999:3x 3x 3x 37

407:11x 37

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

3x 37 = 111

Therefore, the value for common factors is 111.

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 = 13943293749/(1x111)

LCM = 13943293749/111

LCM = 125615259

Thus, we can understand that the LCM of 213,161,999,407 is 125615259.
