Find LCM of 720,992,383,836,703 with Prime Factorization
| 2 | 720, 992, 383, 836, 703 |
| 2 | 360, 496, 383, 418, 703 |
| 2 | 180, 248, 383, 209, 703 |
| 2 | 90, 124, 383, 209, 703 |
| 19 | 45, 62, 383, 209, 703 |
| 45, 62, 383, 11, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 19 x 45 x 62 x 383 x 11 x 37 = 132212028960
Therefore, the lowest common multiple of 720,992,383,836,703 is 132212028960.
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.
720 x 992 x 383 x 836 x 703 = 160769827215360
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.
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
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
383 : 1, 383
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,992,383,836,703, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
992:2x 2x 2x 2x 2x 31
383:383
836:2x 2x 11x 19
703:19x 37
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 19 = 1216
Therefore, the value for common factors is 1216.
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 = 160769827215360/(1x1216)
LCM = 160769827215360/1216
LCM = 132212028960
Thus, we can understand that the LCM of 720,992,383,836,703 is 132212028960.
