Given numbers are 422,990,880,238

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

The LCM of 422,990,880,238 is 198863280.

Find LCM of 422,990,880,238 with Prime Factorization

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

2 x 5 x 11 x 211 x 9 x 8 x 119 = 198863280

Therefore, the lowest common multiple of 422,990,880,238 is 198863280.

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.

422 x 990 x 880 x 238 = 87499843200

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.

422 : 1, 2, 211, 422

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

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

238 : 1, 2, 7, 14, 17, 34, 119, 238

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,990,880,238, is 2.

Now, the common factors can be found like this.

422:2x 211

990:2x 3x 3x 5x 11

880:2x 2x 2x 2x 5x 11

238:2x 7x 17

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 5x 11 = 220

Therefore, the value for common factors is 220.

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 = 87499843200/(2x220)

LCM = 87499843200/440

LCM = 198863280

Thus, we can understand that the LCM of 422,990,880,238 is 198863280.
