Find LCM of 397,836,704,832 with Prime Factorization
| 2 | 397, 836, 704, 832 |
| 2 | 397, 418, 352, 416 |
| 2 | 397, 209, 176, 208 |
| 2 | 397, 209, 88, 104 |
| 2 | 397, 209, 44, 52 |
| 2 | 397, 209, 22, 26 |
| 11 | 397, 209, 11, 13 |
| 397, 19, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 11 x 397 x 19 x 1 x 13 = 69033536
Therefore, the lowest common multiple of 397,836,704,832 is 69033536.
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.
397 x 836 x 704 x 832 = 194398437376
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.
397 : 1, 397
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,836,704,832, is 1.
Now, the common factors can be found like this.
397:397
836:2x 2x 11x 19
704:2x 2x 2x 2x 2x 2x 11
832:2x 2x 2x 2x 2x 2x 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 2x 2x 2x 2x 2x 2x 2x 11 = 2816
Therefore, the value for common factors is 2816.
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 = 194398437376/(1x2816)
LCM = 194398437376/2816
LCM = 69033536
Thus, we can understand that the LCM of 397,836,704,832 is 69033536.
