Given numbers are 660,418,955,990

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

The LCM of 660,418,955,990 is 7185420.

Find LCM of 660,418,955,990 with Prime Factorization

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

2 x 3 x 5 x 11 x 2 x 19 x 191 x 3 = 7185420

Therefore, the lowest common multiple of 660,418,955,990 is 7185420.

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.

660 x 418 x 955 x 990 = 260830746000

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

418 : 1, 2, 11, 19, 22, 38, 209, 418

955 : 1, 5, 191, 955

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,418,955,990, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

418:2x 11x 19

955:5x 191

990:2x 3x 3x 5x 11

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 3x 5x 5x 11x 11 = 36300

Therefore, the value for common factors is 36300.

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 = 260830746000/(1x36300)

LCM = 260830746000/36300

LCM = 7185420

Thus, we can understand that the LCM of 660,418,955,990 is 7185420.
