Find LCM of 664,272,928,391 with Prime Factorization


2 664, 272, 928, 391
2 332, 136, 464, 391
2 166, 68, 232, 391
2 83, 34, 116, 391
17 83, 17, 58, 391
83, 1, 58, 23

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

2 x 2 x 2 x 2 x 17 x 83 x 1 x 58 x 23 = 30116384

Therefore, the lowest common multiple of 664,272,928,391 is 30116384.

LCM Formula to Find Lowest Common Multiple of 664,272,928,391

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.

664 x 272 x 928 x 391 = 65533251584

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.

664 : 1, 2, 4, 8, 83, 166, 332, 664

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,272,928,391, is 1.

Now, the common factors can be found like this.

664:2x 2x 2x 83

272:2x 2x 2x 2x 17

928:2x 2x 2x 2x 2x 29

391:17x 23

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 2x 2x 17 = 2176

Therefore, the value for common factors is 2176.

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 = 65533251584/(1x2176)

LCM = 65533251584/2176

LCM = 30116384

Thus, we can understand that the LCM of 664,272,928,391 is 30116384.
