Given numbers are 214,391,249,990

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

The LCM of 214,391,249,990 is 3437746290.

Find LCM of 214,391,249,990 with Prime Factorization

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

2 x 3 x 107 x 391 x 83 x 165 = 3437746290

Therefore, the lowest common multiple of 214,391,249,990 is 3437746290.

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.

214 x 391 x 249 x 990 = 20626477740

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.

214 : 1, 2, 107, 214

391 : 1, 17, 23, 391

249 : 1, 3, 83, 249

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 214,391,249,990, is 1.

Now, the common factors can be found like this.

214:2x 107

391:17x 23

249:3x 83

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 3 = 6

Therefore, the value for common factors is 6.

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 = 20626477740/(1x6)

LCM = 20626477740/6

LCM = 3437746290

Thus, we can understand that the LCM of 214,391,249,990 is 3437746290.
