Calculate the LCM of 138,419,286,511,820

Given numbers are 138,419,286,511,820

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

The LCM of 138,419,286,511,820 is 1732343072460.

Find LCM of 138,419,286,511,820 with Prime Factorization


2 138, 419, 286, 511, 820
69, 419, 143, 511, 410

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

2 x 69 x 419 x 143 x 511 x 410 = 1732343072460

Therefore, the lowest common multiple of 138,419,286,511,820 is 1732343072460.

LCM Formula to Find Lowest Common Multiple of 138,419,286,511,820

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.

138 x 419 x 286 x 511 x 820 = 6929372289840

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

419 : 1, 419

286 : 1, 2, 11, 13, 22, 26, 143, 286

511 : 1, 7, 73, 511

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,419,286,511,820, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

419:419

286:2x 11x 13

511:7x 73

820:2x 2x 5x 41

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 6929372289840/(1x4)

LCM = 6929372289840/4

LCM = 1732343072460

Thus, we can understand that the LCM of 138,419,286,511,820 is 1732343072460.
