Calculate the LCM of 3,780,731,819

Given numbers are 3,780,731,819

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

The LCM of 3,780,731,819 is 11973780.

Find LCM of 3,780,731,819 with Prime Factorization


3 3, 780, 731, 819
13 1, 260, 731, 273
1, 20, 731, 21

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

3 x 13 x 1 x 20 x 731 x 21 = 11973780

Therefore, the lowest common multiple of 3,780,731,819 is 11973780.

LCM Formula to Find Lowest Common Multiple of 3,780,731,819

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.

3 x 780 x 731 x 819 = 1400932260

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.

3 : 1, 3

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

731 : 1, 17, 43, 731

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,780,731,819, is 1.

Now, the common factors can be found like this.

3:3

780:2x 2x 3x 5x 13

731:17x 43

819:3x 3x 7x 13

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 13 = 117

Therefore, the value for common factors is 117.

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 = 1400932260/(1x117)

LCM = 1400932260/117

LCM = 11973780

Thus, we can understand that the LCM of 3,780,731,819 is 11973780.
