Given numbers are 890,496,256,328
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,496,256,328 is 144792320.
Find LCM of 890,496,256,328 with Prime Factorization
| 2 | 890, 496, 256, 328 |
| 2 | 445, 248, 128, 164 |
| 2 | 445, 124, 64, 82 |
| 2 | 445, 62, 32, 41 |
| 445, 31, 16, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 445 x 31 x 16 x 41 = 144792320
Therefore, the lowest common multiple of 890,496,256,328 is 144792320.
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.
890 x 496 x 256 x 328 = 37066833920
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
328 : 1, 2, 4, 8, 41, 82, 164, 328
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,496,256,328, is 2.
Now, the common factors can be found like this.
890:2x 5x 89
496:2x 2x 2x 2x 31
256:2x 2x 2x 2x 2x 2x 2x 2
328:2x 2x 2x 41
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 2 = 128
Therefore, the value for common factors is 128.
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 = 37066833920/(2x128)
LCM = 37066833920/256
LCM = 144792320
Thus, we can understand that the LCM of 890,496,256,328 is 144792320.
