Given numbers are 165,918,948,390,472

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

The LCM of 165,918,948,390,472 is 12237362280.

Find LCM of 165,918,948,390,472 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 153 x 79 x 13 x 118 = 12237362280

Therefore, the lowest common multiple of 165,918,948,390,472 is 12237362280.

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 918 x 948 x 390 x 472 = 26432702524800

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

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

472 : 1, 2, 4, 8, 59, 118, 236, 472

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,918,948,390,472, is 1.

Now, the common factors can be found like this.

165:3x 5x 11

918:2x 3x 3x 3x 17

948:2x 2x 3x 79

390:2x 3x 5x 13

472:2x 2x 2x 59

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

2x 2x 2x 2x 3x 3x 3x 5 = 2160

Therefore, the value for common factors is 2160.

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 = 26432702524800/(1x2160)

LCM = 26432702524800/2160

LCM = 12237362280

Thus, we can understand that the LCM of 165,918,948,390,472 is 12237362280.
