Find LCM of 924,704,728,169 with Prime Factorization
| 2 | 924, 704, 728, 169 |
| 2 | 462, 352, 364, 169 |
| 2 | 231, 176, 182, 169 |
| 7 | 231, 88, 91, 169 |
| 11 | 33, 88, 13, 169 |
| 13 | 3, 8, 13, 169 |
| 3, 8, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 11 x 13 x 3 x 8 x 1 x 13 = 2498496
Therefore, the lowest common multiple of 924,704,728,169 is 2498496.
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 704 x 728 x 169 = 80031823872
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
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,704,728,169, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
704:2x 2x 2x 2x 2x 2x 11
728:2x 2x 2x 7x 13
169:13x 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 7x 11x 13 = 32032
Therefore, the value for common factors is 32032.
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 = 80031823872/(1x32032)
LCM = 80031823872/32032
LCM = 2498496
Thus, we can understand that the LCM of 924,704,728,169 is 2498496.
