Calculate the LCM of 808,905,899,945

Given numbers are 808,905,899,945

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

The LCM of 808,905,899,945 is 124245719640.

Find LCM of 808,905,899,945 with Prime Factorization


5 808, 905, 899, 945
808, 181, 899, 189

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

5 x 808 x 181 x 899 x 189 = 124245719640

Therefore, the lowest common multiple of 808,905,899,945 is 124245719640.

LCM Formula to Find Lowest Common Multiple of 808,905,899,945

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.

808 x 905 x 899 x 945 = 621228598200

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.

808 : 1, 2, 4, 8, 101, 202, 404, 808

905 : 1, 5, 181, 905

899 : 1, 29, 31, 899

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,905,899,945, is 1.

Now, the common factors can be found like this.

808:2x 2x 2x 101

905:5x 181

899:29x 31

945:3x 3x 3x 5x 7

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

5 = 5

Therefore, the value for common factors is 5.

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 = 621228598200/(1x5)

LCM = 621228598200/5

LCM = 124245719640

Thus, we can understand that the LCM of 808,905,899,945 is 124245719640.
