Given numbers are 561,556,164,857

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

The LCM of 561,556,164,857 is 10959792492.

Find LCM of 561,556,164,857 with Prime Factorization

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

2 x 2 x 561 x 139 x 41 x 857 = 10959792492

Therefore, the lowest common multiple of 561,556,164,857 is 10959792492.

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.

561 x 556 x 164 x 857 = 43839169968

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

556 : 1, 2, 4, 139, 278, 556

164 : 1, 2, 4, 41, 82, 164

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,556,164,857, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

556:2x 2x 139

164:2x 2x 41

857:857

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 43839169968/(1x4)

LCM = 43839169968/4

LCM = 10959792492

Thus, we can understand that the LCM of 561,556,164,857 is 10959792492.
