Find LCM of 135,561,855,891 with Prime Factorization


3 135, 561, 855, 891
3 45, 187, 285, 297
3 15, 187, 95, 99
5 5, 187, 95, 33
11 1, 187, 19, 33
1, 17, 19, 3

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

3 x 3 x 3 x 5 x 11 x 1 x 17 x 19 x 3 = 1438965

Therefore, the lowest common multiple of 135,561,855,891 is 1438965.

LCM Formula to Find Lowest Common Multiple of 135,561,855,891

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.

135 x 561 x 855 x 891 = 57695301675

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.

135 : 1, 3, 5, 9, 15, 27, 45, 135

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

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

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 135,561,855,891, is 3.

Now, the common factors can be found like this.

135:3x 3x 3x 5

561:3x 11x 17

855:3x 3x 5x 19

891:3x 3x 3x 3x 11

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

3x 3x 3x 3x 3x 5x 11 = 13365

Therefore, the value for common factors is 13365.

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 = 57695301675/(3x13365)

LCM = 57695301675/40095

LCM = 1438965

Thus, we can understand that the LCM of 135,561,855,891 is 1438965.
