Calculate the LCM of 189,443,667,990

Given numbers are 189,443,667,990

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

The LCM of 189,443,667,990 is 6143049990.

Find LCM of 189,443,667,990 with Prime Factorization


3 189, 443, 667, 990
3 63, 443, 667, 330
21, 443, 667, 110

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

3 x 3 x 21 x 443 x 667 x 110 = 6143049990

Therefore, the lowest common multiple of 189,443,667,990 is 6143049990.

LCM Formula to Find Lowest Common Multiple of 189,443,667,990

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.

189 x 443 x 667 x 990 = 55287449910

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

443 : 1, 443

667 : 1, 23, 29, 667

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,443,667,990, is 1.

Now, the common factors can be found like this.

189:3x 3x 3x 7

443:443

667:23x 29

990:2x 3x 3x 5x 11

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 = 55287449910/(1x9)

LCM = 55287449910/9

LCM = 6143049990

Thus, we can understand that the LCM of 189,443,667,990 is 6143049990.
