Calculate the LCM of 824,420,179,320

Given numbers are 824,420,179,320

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

The LCM of 824,420,179,320 is 123896640.

Find LCM of 824,420,179,320 with Prime Factorization


2 824, 420, 179, 320
2 412, 210, 179, 160
2 206, 105, 179, 80
5 103, 105, 179, 40
103, 21, 179, 8

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

2 x 2 x 2 x 5 x 103 x 21 x 179 x 8 = 123896640

Therefore, the lowest common multiple of 824,420,179,320 is 123896640.

LCM Formula to Find Lowest Common Multiple of 824,420,179,320

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.

824 x 420 x 179 x 320 = 19823462400

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.

824 : 1, 2, 4, 8, 103, 206, 412, 824

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

179 : 1, 179

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,420,179,320, is 1.

Now, the common factors can be found like this.

824:2x 2x 2x 103

420:2x 2x 3x 5x 7

179:179

320:2x 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 2x 5 = 160

Therefore, the value for common factors is 160.

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 = 19823462400/(1x160)

LCM = 19823462400/160

LCM = 123896640

Thus, we can understand that the LCM of 824,420,179,320 is 123896640.
