The LCM of 462,728,672,993 is 31807776.
Find LCM of 462,728,672,993 with Prime Factorization
| 2 | 462, 728, 672, 993 |
| 2 | 231, 364, 336, 993 |
| 2 | 231, 182, 168, 993 |
| 3 | 231, 91, 84, 993 |
| 7 | 77, 91, 28, 331 |
| 11, 13, 4, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 11 x 13 x 4 x 331 = 31807776
Therefore, the lowest common multiple of 462,728,672,993 is 31807776.
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.
462 x 728 x 672 x 993 = 224435667456
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,728,672,993, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
728:2x 2x 2x 7x 13
672:2x 2x 2x 2x 2x 3x 7
993:3x 331
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 7x 7 = 7056
Therefore, the value for common factors is 7056.
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 = 224435667456/(1x7056)
LCM = 224435667456/7056
LCM = 31807776
Thus, we can understand that the LCM of 462,728,672,993 is 31807776.
