Calculate the LCM of 829,279,138,399

Given numbers are 829,279,138,399

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

The LCM of 829,279,138,399 is 1415038338.

Find LCM of 829,279,138,399 with Prime Factorization


3 829, 279, 138, 399
829, 93, 46, 133

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

3 x 829 x 93 x 46 x 133 = 1415038338

Therefore, the lowest common multiple of 829,279,138,399 is 1415038338.

LCM Formula to Find Lowest Common Multiple of 829,279,138,399

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.

829 x 279 x 138 x 399 = 12735345042

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.

829 : 1, 829

279 : 1, 3, 9, 31, 93, 279

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

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,279,138,399, is 1.

Now, the common factors can be found like this.

829:829

279:3x 3x 31

138:2x 3x 23

399:3x 7x 19

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 12735345042/(1x9)

LCM = 12735345042/9

LCM = 1415038338

Thus, we can understand that the LCM of 829,279,138,399 is 1415038338.
