Find LCM of 621,720,519,784,192 with Prime Factorization
| 2 | 621, 720, 519, 784, 192 |
| 2 | 621, 360, 519, 392, 96 |
| 2 | 621, 180, 519, 196, 48 |
| 2 | 621, 90, 519, 98, 24 |
| 3 | 621, 45, 519, 49, 12 |
| 3 | 207, 15, 173, 49, 4 |
| 69, 5, 173, 49, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 69 x 5 x 173 x 49 x 4 = 1684549440
Therefore, the lowest common multiple of 621,720,519,784,192 is 1684549440.
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.
621 x 720 x 519 x 784 x 192 = 34930817187840
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
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
519 : 1, 3, 173, 519
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,720,519,784,192, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
720:2x 2x 2x 2x 3x 3x 5
519:3x 173
784:2x 2x 2x 2x 7x 7
192:2x 2x 2x 2x 2x 2x 3
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 2x 3x 3x 3x 3 = 20736
Therefore, the value for common factors is 20736.
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 = 34930817187840/(1x20736)
LCM = 34930817187840/20736
LCM = 1684549440
Thus, we can understand that the LCM of 621,720,519,784,192 is 1684549440.
