Given numbers are 794,904,786,256
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 794,904,786,256 is 4513375488.
Find LCM of 794,904,786,256 with Prime Factorization
| 2 | 794, 904, 786, 256 |
| 2 | 397, 452, 393, 128 |
| 2 | 397, 226, 393, 64 |
| 397, 113, 393, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 397 x 113 x 393 x 32 = 4513375488
Therefore, the lowest common multiple of 794,904,786,256 is 4513375488.
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.
794 x 904 x 786 x 256 = 144428015616
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.
794 : 1, 2, 397, 794
904 : 1, 2, 4, 8, 113, 226, 452, 904
786 : 1, 2, 3, 6, 131, 262, 393, 786
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 794,904,786,256, is 2.
Now, the common factors can be found like this.
794:2x 397
904:2x 2x 2x 113
786:2x 3x 131
256:2x 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 2 = 16
Therefore, the value for common factors is 16.
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 = 144428015616/(2x16)
LCM = 144428015616/32
LCM = 4513375488
Thus, we can understand that the LCM of 794,904,786,256 is 4513375488.
