The LCM of 904,846,824,720 is 393863760.
Find LCM of 904,846,824,720 with Prime Factorization
| 2 | 904, 846, 824, 720 |
| 2 | 452, 423, 412, 360 |
| 2 | 226, 423, 206, 180 |
| 3 | 113, 423, 103, 90 |
| 3 | 113, 141, 103, 30 |
| 113, 47, 103, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 113 x 47 x 103 x 10 = 393863760
Therefore, the lowest common multiple of 904,846,824,720 is 393863760.
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.
904 x 846 x 824 x 720 = 453731051520
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
824 : 1, 2, 4, 8, 103, 206, 412, 824
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,846,824,720, is 2.
Now, the common factors can be found like this.
904:2x 2x 2x 113
846:2x 3x 3x 47
824:2x 2x 2x 103
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 3x 3 = 576
Therefore, the value for common factors is 576.
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 = 453731051520/(2x576)
LCM = 453731051520/1152
LCM = 393863760
Thus, we can understand that the LCM of 904,846,824,720 is 393863760.
