Calculate the LCM of 389,494,814,798

Given numbers are 389,494,814,798

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

The LCM of 389,494,814,798 is 1642442802.

Find LCM of 389,494,814,798 with Prime Factorization


2 389, 494, 814, 798
19 389, 247, 407, 399
389, 13, 407, 21

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

2 x 19 x 389 x 13 x 407 x 21 = 1642442802

Therefore, the lowest common multiple of 389,494,814,798 is 1642442802.

LCM Formula to Find Lowest Common Multiple of 389,494,814,798

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.

389 x 494 x 814 x 798 = 124825652952

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.

389 : 1, 389

494 : 1, 2, 13, 19, 26, 38, 247, 494

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

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,494,814,798, is 1.

Now, the common factors can be found like this.

389:389

494:2x 13x 19

814:2x 11x 37

798:2x 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.

2x 2x 19 = 76

Therefore, the value for common factors is 76.

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 = 124825652952/(1x76)

LCM = 124825652952/76

LCM = 1642442802

Thus, we can understand that the LCM of 389,494,814,798 is 1642442802.
