Calculate the LCM of 867,561,195,513

Given numbers are 867,561,195,513

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

The LCM of 867,561,195,513 is 106003755.

Find LCM of 867,561,195,513 with Prime Factorization


3 867, 561, 195, 513
17 289, 187, 65, 171
17, 11, 65, 171

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

3 x 17 x 17 x 11 x 65 x 171 = 106003755

Therefore, the lowest common multiple of 867,561,195,513 is 106003755.

LCM Formula to Find Lowest Common Multiple of 867,561,195,513

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.

867 x 561 x 195 x 513 = 48655723545

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.

867 : 1, 3, 17, 51, 289, 867

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

195 : 1, 3, 5, 13, 15, 39, 65, 195

513 : 1, 3, 9, 19, 27, 57, 171, 513

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,561,195,513, is 3.

Now, the common factors can be found like this.

867:3x 17x 17

561:3x 11x 17

195:3x 5x 13

513:3x 3x 3x 19

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 17 = 153

Therefore, the value for common factors is 153.

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 = 48655723545/(3x153)

LCM = 48655723545/459

LCM = 106003755

Thus, we can understand that the LCM of 867,561,195,513 is 106003755.
