Given numbers are 398,311,147,166

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

The LCM of 398,311,147,166 is 1510215378.

Find LCM of 398,311,147,166 with Prime Factorization

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

2 x 199 x 311 x 147 x 83 = 1510215378

Therefore, the lowest common multiple of 398,311,147,166 is 1510215378.

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.

398 x 311 x 147 x 166 = 3020430756

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.

398 : 1, 2, 199, 398

311 : 1, 311

147 : 1, 3, 7, 21, 49, 147

166 : 1, 2, 83, 166

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,311,147,166, is 1.

Now, the common factors can be found like this.

398:2x 199

311:311

147:3x 7x 7

166:2x 83

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 = 3020430756/(1x2)

LCM = 3020430756/2

LCM = 1510215378

Thus, we can understand that the LCM of 398,311,147,166 is 1510215378.

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