Calculate the LCM of 988,990,823,793

Given numbers are 988,990,823,793

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

The LCM of 988,990,823,793 is 24552279180.

Find LCM of 988,990,823,793 with Prime Factorization


2 988, 990, 823, 793
13 494, 495, 823, 793
38, 495, 823, 61

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

2 x 13 x 38 x 495 x 823 x 61 = 24552279180

Therefore, the lowest common multiple of 988,990,823,793 is 24552279180.

LCM Formula to Find Lowest Common Multiple of 988,990,823,793

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.

988 x 990 x 823 x 793 = 638359258680

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.

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

823 : 1, 823

793 : 1, 13, 61, 793

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,990,823,793, is 1.

Now, the common factors can be found like this.

988:2x 2x 13x 19

990:2x 3x 3x 5x 11

823:823

793:13x 61

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 638359258680/(1x26)

LCM = 638359258680/26

LCM = 24552279180

Thus, we can understand that the LCM of 988,990,823,793 is 24552279180.
