Given numbers are 220,928,251,990

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

The LCM of 220,928,251,990 is 115299360.

Find LCM of 220,928,251,990 with Prime Factorization

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

2 x 2 x 5 x 11 x 1 x 232 x 251 x 9 = 115299360

Therefore, the lowest common multiple of 220,928,251,990 is 115299360.

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.

220 x 928 x 251 x 990 = 50731718400

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.

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

251 : 1, 251

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 220,928,251,990, is 1.

Now, the common factors can be found like this.

220:2x 2x 5x 11

928:2x 2x 2x 2x 2x 29

251:251

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 2x 5x 11 = 440

Therefore, the value for common factors is 440.

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 = 50731718400/(1x440)

LCM = 50731718400/440

LCM = 115299360

Thus, we can understand that the LCM of 220,928,251,990 is 115299360.
