Find LCM of 426,231,320,320 with Prime Factorization
| 2 | 426, 231, 320, 320 |
| 2 | 213, 231, 160, 160 |
| 2 | 213, 231, 80, 80 |
| 2 | 213, 231, 40, 40 |
| 2 | 213, 231, 20, 20 |
| 2 | 213, 231, 10, 10 |
| 3 | 213, 231, 5, 5 |
| 5 | 71, 77, 5, 5 |
| 71, 77, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 71 x 77 x 1 x 1 = 5248320
Therefore, the lowest common multiple of 426,231,320,320 is 5248320.
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.
426 x 231 x 320 x 320 = 10076774400
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
231 : 1, 3, 7, 11, 21, 33, 77, 231
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,231,320,320, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
231:3x 7x 11
320:2x 2x 2x 2x 2x 2x 5
320:2x 2x 2x 2x 2x 2x 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 2x 2x 2x 2x 2x 3x 5 = 1920
Therefore, the value for common factors is 1920.
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 = 10076774400/(1x1920)
LCM = 10076774400/1920
LCM = 5248320
Thus, we can understand that the LCM of 426,231,320,320 is 5248320.
