Given numbers are 788,538,120,733,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,538,120,733,819 is 1272525148440.
Find LCM of 788,538,120,733,819 with Prime Factorization
| 2 | 788, 538, 120, 733, 819 |
| 2 | 394, 269, 60, 733, 819 |
| 3 | 197, 269, 30, 733, 819 |
| 197, 269, 10, 733, 273 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 197 x 269 x 10 x 733 x 273 = 1272525148440
Therefore, the lowest common multiple of 788,538,120,733,819 is 1272525148440.
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.
788 x 538 x 120 x 733 x 819 = 30540603562560
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.
788 : 1, 2, 4, 197, 394, 788
538 : 1, 2, 269, 538
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
733 : 1, 733
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,538,120,733,819, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
538:2x 269
120:2x 2x 2x 3x 5
733:733
819:3x 3x 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 3 = 24
Therefore, the value for common factors is 24.
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 = 30540603562560/(1x24)
LCM = 30540603562560/24
LCM = 1272525148440
Thus, we can understand that the LCM of 788,538,120,733,819 is 1272525148440.
