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

The LCM of 924,342,924,640 is 8426880.

Find LCM of 924,342,924,640 with Prime Factorization


2 924, 342, 924, 640
2 462, 171, 462, 320
3 231, 171, 231, 160
7 77, 57, 77, 160
11 11, 57, 11, 160
1, 57, 1, 160

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

2 x 2 x 3 x 7 x 11 x 1 x 57 x 1 x 160 = 8426880

LCM Formula to Find Lowest Common Multiple of 924,342,924,640

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.

924 x 342 x 924 x 640 = 186874490880

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.

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,342,924,640, is 2.

Now, the common factors can be found like this.

924:2x 2x 3x 7x 11

342:2x 3x 3x 19

924:2x 2x 3x 7x 11

640:2x 2x 2x 2x 2x 2x 2x 5

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 2x 3x 3x 7x 11 = 11088

Therefore, the value for common factors is 11088.

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 = 186874490880/(2x11088)

LCM = 186874490880/22176

LCM = 8426880

Thus, we can understand that the LCM of 924,342,924,640 is 8426880.
