Calculate the LCM of 311,158,442,390,266

Given numbers are 311,158,442,390,266

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

The LCM of 311,158,442,390,266 is 21664698510.

Find LCM of 311,158,442,390,266 with Prime Factorization


2 311, 158, 442, 390, 266
13 311, 79, 221, 195, 133
311, 79, 17, 15, 133

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

2 x 13 x 311 x 79 x 17 x 15 x 133 = 21664698510

Therefore, the lowest common multiple of 311,158,442,390,266 is 21664698510.

LCM Formula to Find Lowest Common Multiple of 311,158,442,390,266

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.

311 x 158 x 442 x 390 x 266 = 2253128645040

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.

311 : 1, 311

158 : 1, 2, 79, 158

442 : 1, 2, 13, 17, 26, 34, 221, 442

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

266 : 1, 2, 7, 14, 19, 38, 133, 266

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,158,442,390,266, is 1.

Now, the common factors can be found like this.

311:311

158:2x 79

442:2x 13x 17

390:2x 3x 5x 13

266:2x 7x 19

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 2x 13 = 104

Therefore, the value for common factors is 104.

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 = 2253128645040/(1x104)

LCM = 2253128645040/104

LCM = 21664698510

Thus, we can understand that the LCM of 311,158,442,390,266 is 21664698510.
