Calculate the LCM of 171,644,891,865,435

Given numbers are 171,644,891,865,435

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

The LCM of 171,644,891,865,435 is 273483593460.

Find LCM of 171,644,891,865,435 with Prime Factorization


3 171, 644, 891, 865, 435
3 57, 644, 297, 865, 145
5 19, 644, 99, 865, 145
19, 644, 99, 173, 29

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

3 x 3 x 5 x 19 x 644 x 99 x 173 x 29 = 273483593460

Therefore, the lowest common multiple of 171,644,891,865,435 is 273483593460.

LCM Formula to Find Lowest Common Multiple of 171,644,891,865,435

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.

171 x 644 x 891 x 865 x 435 = 36920285117100

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.

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

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

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

865 : 1, 5, 173, 865

435 : 1, 3, 5, 15, 29, 87, 145, 435

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,644,891,865,435, is 1.

Now, the common factors can be found like this.

171:3x 3x 19

644:2x 2x 7x 23

891:3x 3x 3x 3x 11

865:5x 173

435:3x 5x 29

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 5 = 135

Therefore, the value for common factors is 135.

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 = 36920285117100/(1x135)

LCM = 36920285117100/135

LCM = 273483593460

Thus, we can understand that the LCM of 171,644,891,865,435 is 273483593460.
