Find LCM of 920,728,510,880,993 with Prime Factorization
| 2 | 920, 728, 510, 880, 993 |
| 2 | 460, 364, 255, 440, 993 |
| 2 | 230, 182, 255, 220, 993 |
| 3 | 115, 91, 255, 110, 993 |
| 5 | 115, 91, 85, 110, 331 |
| 23, 91, 17, 22, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 23 x 91 x 17 x 22 x 331 = 31092101040
Therefore, the lowest common multiple of 920,728,510,880,993 is 31092101040.
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.
920 x 728 x 510 x 880 x 993 = 298484169984000
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,728,510,880,993, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
728:2x 2x 2x 7x 13
510:2x 3x 5x 17
880:2x 2x 2x 2x 5x 11
993:3x 331
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 3x 5x 5 = 9600
Therefore, the value for common factors is 9600.
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 = 298484169984000/(1x9600)
LCM = 298484169984000/9600
LCM = 31092101040
Thus, we can understand that the LCM of 920,728,510,880,993 is 31092101040.
