Calculate the LCM of 231,870,814,342

Given numbers are 231,870,814,342

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

The LCM of 231,870,814,342 is 141281910.

Find LCM of 231,870,814,342 with Prime Factorization


2 231, 870, 814, 342
3 231, 435, 407, 171
11 77, 145, 407, 57
7, 145, 37, 57

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

2 x 3 x 11 x 7 x 145 x 37 x 57 = 141281910

Therefore, the lowest common multiple of 231,870,814,342 is 141281910.

LCM Formula to Find Lowest Common Multiple of 231,870,814,342

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.

231 x 870 x 814 x 342 = 55947636360

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.

231 : 1, 3, 7, 11, 21, 33, 77, 231

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

814 : 1, 2, 11, 22, 37, 74, 407, 814

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,870,814,342, is 1.

Now, the common factors can be found like this.

231:3x 7x 11

870:2x 3x 5x 29

814:2x 11x 37

342:2x 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.

2x 2x 3x 3x 11 = 396

Therefore, the value for common factors is 396.

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 = 55947636360/(1x396)

LCM = 55947636360/396

LCM = 141281910

Thus, we can understand that the LCM of 231,870,814,342 is 141281910.
