Find LCM of 763,616,448,128 with Prime Factorization
| 2 | 763, 616, 448, 128 |
| 2 | 763, 308, 224, 64 |
| 2 | 763, 154, 112, 32 |
| 2 | 763, 77, 56, 16 |
| 2 | 763, 77, 28, 8 |
| 2 | 763, 77, 14, 4 |
| 7 | 763, 77, 7, 2 |
| 109, 11, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 7 x 109 x 11 x 1 x 2 = 1074304
Therefore, the lowest common multiple of 763,616,448,128 is 1074304.
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.
763 x 616 x 448 x 128 = 26952138752
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.
763 : 1, 7, 109, 763
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,616,448,128, is 1.
Now, the common factors can be found like this.
763:7x 109
616:2x 2x 2x 7x 11
448:2x 2x 2x 2x 2x 2x 7
128:2x 2x 2x 2x 2x 2x 2
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 2x 7x 7 = 25088
Therefore, the value for common factors is 25088.
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 = 26952138752/(1x25088)
LCM = 26952138752/25088
LCM = 1074304
Thus, we can understand that the LCM of 763,616,448,128 is 1074304.
