Calculate the LCM of 238,442,309

Given numbers are 238,442,309

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

The LCM of 238,442,309 is 956046.

Find LCM of 238,442,309 with Prime Factorization


2 238, 442, 309
17 119, 221, 309
7, 13, 309

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

2 x 17 x 7 x 13 x 309 = 956046

Therefore, the lowest common multiple of 238,442,309 is 956046.

LCM Formula to Find Lowest Common Multiple of 238,442,309

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.

238 x 442 x 309 = 32505564

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.

238 : 1, 2, 7, 14, 17, 34, 119, 238

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

309 : 1, 3, 103, 309

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,442,309, is 1.

Now, the common factors can be found like this.

238:2x 7x 17

442:2x 13x 17

309:3x 103

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 32505564/(1x34)

LCM = 32505564/34

LCM = 956046

Thus, we can understand that the LCM of 238,442,309 is 956046.
