Given numbers are 7,285,796,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,285,796,380 is 1588020.
Find LCM of 7,285,796,380 with Prime Factorization
| 2 | 7, 285, 796, 380 |
| 2 | 7, 285, 398, 190 |
| 5 | 7, 285, 199, 95 |
| 19 | 7, 57, 199, 19 |
| 7, 3, 199, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 7 x 3 x 199 x 1 = 1588020
Therefore, the lowest common multiple of 7,285,796,380 is 1588020.
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.
7 x 285 x 796 x 380 = 603447600
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.
7 : 1, 7
285 : 1, 3, 5, 15, 19, 57, 95, 285
796 : 1, 2, 4, 199, 398, 796
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,285,796,380, is 1.
Now, the common factors can be found like this.
7:7
285:3x 5x 19
796:2x 2x 199
380:2x 2x 5x 19
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 5x 19 = 380
Therefore, the value for common factors is 380.
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 = 603447600/(1x380)
LCM = 603447600/380
LCM = 1588020
Thus, we can understand that the LCM of 7,285,796,380 is 1588020.
