Calculate the LCM of 317,354,442,143

Given numbers are 317,354,442,143

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

The LCM of 317,354,442,143 is 272801958.

Find LCM of 317,354,442,143 with Prime Factorization


2 317, 354, 442, 143
13 317, 177, 221, 143
317, 177, 17, 11

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

2 x 13 x 317 x 177 x 17 x 11 = 272801958

Therefore, the lowest common multiple of 317,354,442,143 is 272801958.

LCM Formula to Find Lowest Common Multiple of 317,354,442,143

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.

317 x 354 x 442 x 143 = 7092850908

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.

317 : 1, 317

354 : 1, 2, 3, 6, 59, 118, 177, 354

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

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,354,442,143, is 1.

Now, the common factors can be found like this.

317:317

354:2x 3x 59

442:2x 13x 17

143:11x 13

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 7092850908/(1x26)

LCM = 7092850908/26

LCM = 272801958

Thus, we can understand that the LCM of 317,354,442,143 is 272801958.
