Find LCM of 414,305,756,120,805 with Prime Factorization
| 2 | 414, 305, 756, 120, 805 |
| 2 | 207, 305, 378, 60, 805 |
| 3 | 207, 305, 189, 30, 805 |
| 3 | 69, 305, 63, 10, 805 |
| 5 | 23, 305, 21, 10, 805 |
| 7 | 23, 61, 21, 2, 161 |
| 23 | 23, 61, 3, 2, 23 |
| 1, 61, 3, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 23 x 1 x 61 x 3 x 2 x 1 = 10606680
Therefore, the lowest common multiple of 414,305,756,120,805 is 10606680.
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.
414 x 305 x 756 x 120 x 805 = 9221447592000
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.
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
305 : 1, 5, 61, 305
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 414,305,756,120,805, is 1.
Now, the common factors can be found like this.
414:2x 3x 3x 23
305:5x 61
756:2x 2x 3x 3x 3x 7
120:2x 2x 2x 3x 5
805:5x 7x 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 3x 3x 3x 5x 5x 7x 23 = 869400
Therefore, the value for common factors is 869400.
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 = 9221447592000/(1x869400)
LCM = 9221447592000/869400
LCM = 10606680
Thus, we can understand that the LCM of 414,305,756,120,805 is 10606680.
