Given numbers are 636,424,796,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,424,796,728 is 23034648.
Find LCM of 636,424,796,728 with Prime Factorization
| 2 | 636, 424, 796, 728 |
| 2 | 318, 212, 398, 364 |
| 2 | 159, 106, 199, 182 |
| 53 | 159, 53, 199, 91 |
| 3, 1, 199, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 53 x 3 x 1 x 199 x 91 = 23034648
Therefore, the lowest common multiple of 636,424,796,728 is 23034648.
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.
636 x 424 x 796 x 728 = 156267052032
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
424 : 1, 2, 4, 8, 53, 106, 212, 424
796 : 1, 2, 4, 199, 398, 796
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,424,796,728, is 4.
Now, the common factors can be found like this.
636:2x 2x 3x 53
424:2x 2x 2x 53
796:2x 2x 199
728:2x 2x 2x 7x 13
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 53 = 1696
Therefore, the value for common factors is 1696.
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 = 156267052032/(4x1696)
LCM = 156267052032/6784
LCM = 23034648
Thus, we can understand that the LCM of 636,424,796,728 is 23034648.
