Find LCM of 884,520,672,561 with Prime Factorization
| 2 | 884, 520, 672, 561 |
| 2 | 442, 260, 336, 561 |
| 2 | 221, 130, 168, 561 |
| 3 | 221, 65, 84, 561 |
| 13 | 221, 65, 28, 187 |
| 17 | 17, 5, 28, 187 |
| 1, 5, 28, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 17 x 1 x 5 x 28 x 11 = 8168160
Therefore, the lowest common multiple of 884,520,672,561 is 8168160.
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.
884 x 520 x 672 x 561 = 173295682560
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.
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 884,520,672,561, is 1.
Now, the common factors can be found like this.
884:2x 2x 13x 17
520:2x 2x 2x 5x 13
672:2x 2x 2x 2x 2x 3x 7
561:3x 11x 17
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 3x 13x 17 = 21216
Therefore, the value for common factors is 21216.
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 = 173295682560/(1x21216)
LCM = 173295682560/21216
LCM = 8168160
Thus, we can understand that the LCM of 884,520,672,561 is 8168160.
