Calculate the LCM of 843,320,876,819

Given numbers are 843,320,876,819

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

The LCM of 843,320,876,819 is 5376047040.

Find LCM of 843,320,876,819 with Prime Factorization


2 843, 320, 876, 819
2 843, 160, 438, 819
3 843, 80, 219, 819
281, 80, 73, 273

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

2 x 2 x 3 x 281 x 80 x 73 x 273 = 5376047040

Therefore, the lowest common multiple of 843,320,876,819 is 5376047040.

LCM Formula to Find Lowest Common Multiple of 843,320,876,819

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.

843 x 320 x 876 x 819 = 193537693440

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.

843 : 1, 3, 281, 843

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

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 843,320,876,819, is 1.

Now, the common factors can be found like this.

843:3x 281

320:2x 2x 2x 2x 2x 2x 5

876:2x 2x 3x 73

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.

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 193537693440/(1x36)

LCM = 193537693440/36

LCM = 5376047040

Thus, we can understand that the LCM of 843,320,876,819 is 5376047040.
