Given numbers are 1,998,278,217

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

The LCM of 1,998,278,217 is 30102674.

Find LCM of 1,998,278,217 with Prime Factorization

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

2 x 1 x 499 x 139 x 217 = 30102674

Therefore, the lowest common multiple of 1,998,278,217 is 30102674.

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.

1 x 998 x 278 x 217 = 60205348

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.

1 : 1

998 : 1, 2, 499, 998

278 : 1, 2, 139, 278

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,998,278,217, is 1.

Now, the common factors can be found like this.

1:

998:2x 499

278:2x 139

217:7x 31

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 60205348/(1x2)

LCM = 60205348/2

LCM = 30102674

Thus, we can understand that the LCM of 1,998,278,217 is 30102674.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 3, 910, 629, 999
