Given numbers are 728,216,914,672
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 728,216,914,672 is 35931168.
Find LCM of 728,216,914,672 with Prime Factorization
| 2 | 728, 216, 914, 672 |
| 2 | 364, 108, 457, 336 |
| 2 | 182, 54, 457, 168 |
| 3 | 91, 27, 457, 84 |
| 7 | 91, 9, 457, 28 |
| 13, 9, 457, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 9 x 457 x 4 = 35931168
Therefore, the lowest common multiple of 728,216,914,672 is 35931168.
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.
728 x 216 x 914 x 672 = 96582979584
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
914 : 1, 2, 457, 914
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,216,914,672, is 2.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
216:2x 2x 2x 3x 3x 3
914:2x 457
672:2x 2x 2x 2x 2x 3x 7
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 7 = 1344
Therefore, the value for common factors is 1344.
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 = 96582979584/(2x1344)
LCM = 96582979584/2688
LCM = 35931168
Thus, we can understand that the LCM of 728,216,914,672 is 35931168.
