Given numbers are 194,430,480,990

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

The LCM of 194,430,480,990 is 66068640.

Find LCM of 194,430,480,990 with Prime Factorization

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

2 x 3 x 5 x 97 x 43 x 16 x 33 = 66068640

Therefore, the lowest common multiple of 194,430,480,990 is 66068640.

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.

194 x 430 x 480 x 990 = 39641184000

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.

194 : 1, 2, 97, 194

430 : 1, 2, 5, 10, 43, 86, 215, 430

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,430,480,990, is 2.

Now, the common factors can be found like this.

194:2x 97

430:2x 5x 43

480:2x 2x 2x 2x 2x 3x 5

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 5 = 300

Therefore, the value for common factors is 300.

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 = 39641184000/(2x300)

LCM = 39641184000/600

LCM = 66068640

Thus, we can understand that the LCM of 194,430,480,990 is 66068640.
