The LCM of 323,606,720,702,445 is 81528791760.
Find LCM of 323,606,720,702,445 with Prime Factorization
| 2 | 323, 606, 720, 702, 445 |
| 3 | 323, 303, 360, 351, 445 |
| 3 | 323, 101, 120, 117, 445 |
| 5 | 323, 101, 40, 39, 445 |
| 323, 101, 8, 39, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 323 x 101 x 8 x 39 x 89 = 81528791760
Therefore, the lowest common multiple of 323,606,720,702,445 is 81528791760.
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.
323 x 606 x 720 x 702 x 445 = 44025547550400
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.
323 : 1, 17, 19, 323
606 : 1, 2, 3, 6, 101, 202, 303, 606
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
445 : 1, 5, 89, 445
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,606,720,702,445, is 1.
Now, the common factors can be found like this.
323:17x 19
606:2x 3x 101
720:2x 2x 2x 2x 3x 3x 5
702:2x 3x 3x 3x 13
445:5x 89
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 44025547550400/(1x540)
LCM = 44025547550400/540
LCM = 81528791760
Thus, we can understand that the LCM of 323,606,720,702,445 is 81528791760.
