Find LCM of 192,280,128,916 with Prime Factorization
| 2 | 192, 280, 128, 916 |
| 2 | 96, 140, 64, 458 |
| 2 | 48, 70, 32, 229 |
| 2 | 24, 35, 16, 229 |
| 2 | 12, 35, 8, 229 |
| 2 | 6, 35, 4, 229 |
| 3, 35, 2, 229 |
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 35 x 2 x 229 = 3077760
Therefore, the lowest common multiple of 192,280,128,916 is 3077760.
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.
192 x 280 x 128 x 916 = 6303252480
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.
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
128 : 1, 2, 4, 8, 16, 32, 64, 128
916 : 1, 2, 4, 229, 458, 916
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,280,128,916, is 4.
Now, the common factors can be found like this.
192:2x 2x 2x 2x 2x 2x 3
280:2x 2x 2x 5x 7
128:2x 2x 2x 2x 2x 2x 2
916:2x 2x 229
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 2 = 512
Therefore, the value for common factors is 512.
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 = 6303252480/(4x512)
LCM = 6303252480/2048
LCM = 3077760
Thus, we can understand that the LCM of 192,280,128,916 is 3077760.
