Given numbers are 936,789,452,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 936,789,452,405 is 1251764280.
Find LCM of 936,789,452,405 with Prime Factorization
| 2 | 936, 789, 452, 405 |
| 2 | 468, 789, 226, 405 |
| 3 | 234, 789, 113, 405 |
| 3 | 78, 263, 113, 135 |
| 26, 263, 113, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 26 x 263 x 113 x 45 = 1251764280
Therefore, the lowest common multiple of 936,789,452,405 is 1251764280.
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.
936 x 789 x 452 x 405 = 135190542240
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.
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
789 : 1, 3, 263, 789
452 : 1, 2, 4, 113, 226, 452
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 936,789,452,405, is 1.
Now, the common factors can be found like this.
936:2x 2x 2x 3x 3x 13
789:3x 263
452:2x 2x 113
405:3x 3x 3x 3x 5
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 135190542240/(1x108)
LCM = 135190542240/108
LCM = 1251764280
Thus, we can understand that the LCM of 936,789,452,405 is 1251764280.
