Find LCM of 378,150,140,459 with Prime Factorization
| 2 | 378, 150, 140, 459 |
| 3 | 189, 75, 70, 459 |
| 3 | 63, 25, 70, 153 |
| 3 | 21, 25, 70, 51 |
| 5 | 7, 25, 70, 17 |
| 7 | 7, 5, 14, 17 |
| 1, 5, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 7 x 1 x 5 x 2 x 17 = 321300
Therefore, the lowest common multiple of 378,150,140,459 is 321300.
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.
378 x 150 x 140 x 459 = 3643542000
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
459 : 1, 3, 9, 17, 27, 51, 153, 459
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,150,140,459, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
150:2x 3x 5x 5
140:2x 2x 5x 7
459:3x 3x 3x 17
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 3x 3x 5x 7 = 11340
Therefore, the value for common factors is 11340.
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 = 3643542000/(1x11340)
LCM = 3643542000/11340
LCM = 321300
Thus, we can understand that the LCM of 378,150,140,459 is 321300.
