Given numbers are 990,626,422,438

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

The LCM of 990,626,422,438 is 4772927610.

Find LCM of 990,626,422,438 with Prime Factorization

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

2 x 3 x 165 x 313 x 211 x 73 = 4772927610

Therefore, the lowest common multiple of 990,626,422,438 is 4772927610.

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.

990 x 626 x 422 x 438 = 114550262640

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.

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

626 : 1, 2, 313, 626

422 : 1, 2, 211, 422

438 : 1, 2, 3, 6, 73, 146, 219, 438

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,626,422,438, is 2.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

626:2x 313

422:2x 211

438:2x 3x 73

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 3 = 12

Therefore, the value for common factors is 12.

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 = 114550262640/(2x12)

LCM = 114550262640/24

LCM = 4772927610

Thus, we can understand that the LCM of 990,626,422,438 is 4772927610.
