Given numbers are 855,943,164,161

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

The LCM of 855,943,164,161 is 22575420.

Find LCM of 855,943,164,161 with Prime Factorization

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

23 x 41 x 855 x 1 x 4 x 7 = 22575420

Therefore, the lowest common multiple of 855,943,164,161 is 22575420.

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.

855 x 943 x 164 x 161 = 21288621060

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

943 : 1, 23, 41, 943

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

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,943,164,161, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

943:23x 41

164:2x 2x 41

161:7x 23

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

23x 41 = 943

Therefore, the value for common factors is 943.

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 = 21288621060/(1x943)

LCM = 21288621060/943

LCM = 22575420

Thus, we can understand that the LCM of 855,943,164,161 is 22575420.
