Given numbers are 789,451,195,456,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,451,195,456,140 is 24609825240.
Find LCM of 789,451,195,456,140 with Prime Factorization
| 2 | 789, 451, 195, 456, 140 |
| 2 | 789, 451, 195, 228, 70 |
| 3 | 789, 451, 195, 114, 35 |
| 5 | 263, 451, 65, 38, 35 |
| 263, 451, 13, 38, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 263 x 451 x 13 x 38 x 7 = 24609825240
Therefore, the lowest common multiple of 789,451,195,456,140 is 24609825240.
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 451 x 195 x 456 x 140 = 4429768543200
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
451 : 1, 11, 41, 451
195 : 1, 3, 5, 13, 15, 39, 65, 195
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,451,195,456,140, is 1.
Now, the common factors can be found like this.
789:3x 263
451:11x 41
195:3x 5x 13
456:2x 2x 2x 3x 19
140:2x 2x 5x 7
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 5 = 180
Therefore, the value for common factors is 180.
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 = 4429768543200/(1x180)
LCM = 4429768543200/180
LCM = 24609825240
Thus, we can understand that the LCM of 789,451,195,456,140 is 24609825240.
