Find LCM of 867,160,640,369 with Prime Factorization
| 2 | 867, 160, 640, 369 |
| 2 | 867, 80, 320, 369 |
| 2 | 867, 40, 160, 369 |
| 2 | 867, 20, 80, 369 |
| 2 | 867, 10, 40, 369 |
| 3 | 867, 5, 20, 369 |
| 5 | 289, 5, 20, 123 |
| 289, 1, 4, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 289 x 1 x 4 x 123 = 68250240
Therefore, the lowest common multiple of 867,160,640,369 is 68250240.
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.
867 x 160 x 640 x 369 = 32760115200
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.
867 : 1, 3, 17, 51, 289, 867
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
369 : 1, 3, 9, 41, 123, 369
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,160,640,369, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
160:2x 2x 2x 2x 2x 5
640:2x 2x 2x 2x 2x 2x 2x 5
369:3x 3x 41
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 2x 2x 2x 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 32760115200/(1x480)
LCM = 32760115200/480
LCM = 68250240
Thus, we can understand that the LCM of 867,160,640,369 is 68250240.
