Find LCM of 416,948,465,788,405 with Prime Factorization
| 2 | 416, 948, 465, 788, 405 |
| 2 | 208, 474, 465, 394, 405 |
| 3 | 104, 237, 465, 197, 405 |
| 5 | 104, 79, 155, 197, 135 |
| 104, 79, 31, 197, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 104 x 79 x 31 x 197 x 27 = 81283681440
Therefore, the lowest common multiple of 416,948,465,788,405 is 81283681440.
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.
416 x 948 x 465 x 788 x 405 = 58524250636800
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.
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
465 : 1, 3, 5, 15, 31, 93, 155, 465
788 : 1, 2, 4, 197, 394, 788
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,948,465,788,405, is 1.
Now, the common factors can be found like this.
416:2x 2x 2x 2x 2x 13
948:2x 2x 3x 79
465:3x 5x 31
788:2x 2x 197
405:3x 3x 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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 58524250636800/(1x720)
LCM = 58524250636800/720
LCM = 81283681440
Thus, we can understand that the LCM of 416,948,465,788,405 is 81283681440.
