Find LCM of 640,320,229,652 with Prime Factorization
| 2 | 640, 320, 229, 652 |
| 2 | 320, 160, 229, 326 |
| 2 | 80, 160, 229, 163 |
| 2 | 40, 80, 229, 163 |
| 2 | 20, 40, 229, 163 |
| 2 | 10, 20, 229, 163 |
| 5 | 5, 10, 229, 163 |
| 1, 2, 229, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 5 x 1 x 2 x 229 x 163 = 23889280
Therefore, the lowest common multiple of 640,320,229,652 is 23889280.
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.
640 x 320 x 229 x 652 = 30578278400
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
229 : 1, 229
652 : 1, 2, 4, 163, 326, 652
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,320,229,652, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
320:2x 2x 2x 2x 2x 2x 5
229:229
652:2x 2x 163
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 2x 2x 2x 5 = 1280
Therefore, the value for common factors is 1280.
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 = 30578278400/(1x1280)
LCM = 30578278400/1280
LCM = 23889280
Thus, we can understand that the LCM of 640,320,229,652 is 23889280.
