Given numbers are 915,903,129,989,396

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

The LCM of 915,903,129,989,396 is 836159940.

Find LCM of 915,903,129,989,396 with Prime Factorization

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

3 x 43 x 305 x 7 x 1 x 23 x 132 = 836159940

Therefore, the lowest common multiple of 915,903,129,989,396 is 836159940.

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.

915 x 903 x 129 x 989 x 396 = 41743612684620

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.

915 : 1, 3, 5, 15, 61, 183, 305, 915

903 : 1, 3, 7, 21, 43, 129, 301, 903

129 : 1, 3, 43, 129

989 : 1, 23, 43, 989

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,903,129,989,396, is 1.

Now, the common factors can be found like this.

915:3x 5x 61

903:3x 7x 43

129:3x 43

989:23x 43

396:2x 2x 3x 3x 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 3x 3x 43x 43 = 49923

Therefore, the value for common factors is 49923.

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 = 41743612684620/(1x49923)

LCM = 41743612684620/49923

LCM = 836159940

Thus, we can understand that the LCM of 915,903,129,989,396 is 836159940.
