Calculate the LCM of 810,217,463,403,561

Given numbers are 810,217,463,403,561

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

The LCM of 810,217,463,403,561 is 197838450810.

Find LCM of 810,217,463,403,561 with Prime Factorization


3 810, 217, 463, 403, 561
31 270, 217, 463, 403, 187
270, 7, 463, 13, 187

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

3 x 31 x 270 x 7 x 463 x 13 x 187 = 197838450810

Therefore, the lowest common multiple of 810,217,463,403,561 is 197838450810.

LCM Formula to Find Lowest Common Multiple of 810,217,463,403,561

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.

810 x 217 x 463 x 403 x 561 = 18398975925330

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.

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

217 : 1, 7, 31, 217

463 : 1, 463

403 : 1, 13, 31, 403

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,217,463,403,561, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

217:7x 31

463:463

403:13x 31

561:3x 11x 17

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

3x 31 = 93

Therefore, the value for common factors is 93.

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 = 18398975925330/(1x93)

LCM = 18398975925330/93

LCM = 197838450810

Thus, we can understand that the LCM of 810,217,463,403,561 is 197838450810.
