Find LCM of 720,382,907,784,720 with Prime Factorization
| 2 | 720, 382, 907, 784, 720 |
| 2 | 360, 191, 907, 392, 360 |
| 2 | 180, 191, 907, 196, 180 |
| 2 | 90, 191, 907, 98, 90 |
| 3 | 45, 191, 907, 49, 45 |
| 3 | 15, 191, 907, 49, 15 |
| 5 | 5, 191, 907, 49, 5 |
| 1, 191, 907, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 5 x 1 x 191 x 907 x 49 x 1 = 6111801360
Therefore, the lowest common multiple of 720,382,907,784,720 is 6111801360.
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 382 x 907 x 784 x 720 = 140815903334400
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
382 : 1, 2, 191, 382
907 : 1, 907
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,382,907,784,720, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
382:2x 191
907:907
784:2x 2x 2x 2x 7x 7
720:2x 2x 2x 2x 3x 3x 5
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 2x 3x 3x 5 = 23040
Therefore, the value for common factors is 23040.
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 = 140815903334400/(1x23040)
LCM = 140815903334400/23040
LCM = 6111801360
Thus, we can understand that the LCM of 720,382,907,784,720 is 6111801360.
