Given numbers are 165,905,243,403

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

The LCM of 165,905,243,403 is 974883195.

Find LCM of 165,905,243,403 with Prime Factorization

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

3 x 5 x 11 x 181 x 81 x 403 = 974883195

Therefore, the lowest common multiple of 165,905,243,403 is 974883195.

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.

165 x 905 x 243 x 403 = 14623247925

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.

165 : 1, 3, 5, 11, 15, 33, 55, 165

905 : 1, 5, 181, 905

243 : 1, 3, 9, 27, 81, 243

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,905,243,403, is 1.

Now, the common factors can be found like this.

165:3x 5x 11

905:5x 181

243:3x 3x 3x 3x 3

403:13x 31

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 14623247925/(1x15)

LCM = 14623247925/15

LCM = 974883195

Thus, we can understand that the LCM of 165,905,243,403 is 974883195.
