Given numbers are 198,514,638

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

The LCM of 198,514,638 is 1475694.

Find LCM of 198,514,638 with Prime Factorization

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

2 x 11 x 9 x 257 x 29 = 1475694

Therefore, the lowest common multiple of 198,514,638 is 1475694.

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.

198 x 514 x 638 = 64930536

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.

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

514 : 1, 2, 257, 514

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,514,638, is 2.

Now, the common factors can be found like this.

198:2x 3x 3x 11

514:2x 257

638:2x 11x 29

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 64930536/(2x22)

LCM = 64930536/44

LCM = 1475694

Thus, we can understand that the LCM of 198,514,638 is 1475694.

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

• LCM of 780, 842, 810
