Find LCM of 623,907,816,240 with Prime Factorization
| 2 | 623, 907, 816, 240 |
| 2 | 623, 907, 408, 120 |
| 2 | 623, 907, 204, 60 |
| 2 | 623, 907, 102, 30 |
| 3 | 623, 907, 51, 15 |
| 623, 907, 17, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 623 x 907 x 17 x 5 = 2305448880
Therefore, the lowest common multiple of 623,907,816,240 is 2305448880.
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.
623 x 907 x 816 x 240 = 110661546240
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.
623 : 1, 7, 89, 623
907 : 1, 907
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,907,816,240, is 1.
Now, the common factors can be found like this.
623:7x 89
907:907
816:2x 2x 2x 2x 3x 17
240:2x 2x 2x 2x 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 3 = 48
Therefore, the value for common factors is 48.
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 = 110661546240/(1x48)
LCM = 110661546240/48
LCM = 2305448880
Thus, we can understand that the LCM of 623,907,816,240 is 2305448880.
