Given numbers are 165,940,990,429

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

The LCM of 165,940,990,429 is 1209780.

Find LCM of 165,940,990,429 with Prime Factorization

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

2 x 3 x 5 x 11 x 1 x 94 x 3 x 13 = 1209780

Therefore, the lowest common multiple of 165,940,990,429 is 1209780.

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 940 x 990 x 429 = 65872521000

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

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

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

429 : 1, 3, 11, 13, 33, 39, 143, 429

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,940,990,429, is 1.

Now, the common factors can be found like this.

165:3x 5x 11

940:2x 2x 5x 47

990:2x 3x 3x 5x 11

429:3x 11x 13

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

2x 3x 3x 5x 5x 11x 11 = 54450

Therefore, the value for common factors is 54450.

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 = 65872521000/(1x54450)

LCM = 65872521000/54450

LCM = 1209780

Thus, we can understand that the LCM of 165,940,990,429 is 1209780.
