Given numbers are 789,903,749,341,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,903,749,341,380 is 3292799234340.
Find LCM of 789,903,749,341,380 with Prime Factorization
| 3 | 789, 903, 749, 341, 380 |
| 7 | 263, 301, 749, 341, 380 |
| 263, 43, 107, 341, 380 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 263 x 43 x 107 x 341 x 380 = 3292799234340
Therefore, the lowest common multiple of 789,903,749,341,380 is 3292799234340.
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.
789 x 903 x 749 x 341 x 380 = 69148783921140
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.
789 : 1, 3, 263, 789
903 : 1, 3, 7, 21, 43, 129, 301, 903
749 : 1, 7, 107, 749
341 : 1, 11, 31, 341
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 789,903,749,341,380, is 1.
Now, the common factors can be found like this.
789:3x 263
903:3x 7x 43
749:7x 107
341:11x 31
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.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 69148783921140/(1x21)
LCM = 69148783921140/21
LCM = 3292799234340
Thus, we can understand that the LCM of 789,903,749,341,380 is 3292799234340.
