Find LCM of 4,978,224,896 with Prime Factorization
| 2 | 4, 978, 224, 896 |
| 2 | 2, 489, 112, 448 |
| 2 | 1, 489, 56, 224 |
| 2 | 1, 489, 28, 112 |
| 2 | 1, 489, 14, 56 |
| 7 | 1, 489, 7, 28 |
| 1, 489, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 7 x 1 x 489 x 1 x 4 = 438144
Therefore, the lowest common multiple of 4,978,224,896 is 438144.
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.
4 x 978 x 224 x 896 = 785154048
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.
4 : 1, 2, 4
978 : 1, 2, 3, 6, 163, 326, 489, 978
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4,978,224,896, is 2.
Now, the common factors can be found like this.
4:2x 2
978:2x 3x 163
224:2x 2x 2x 2x 2x 7
896:2x 2x 2x 2x 2x 2x 2x 7
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 7 = 896
Therefore, the value for common factors is 896.
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 = 785154048/(2x896)
LCM = 785154048/1792
LCM = 438144
Thus, we can understand that the LCM of 4,978,224,896 is 438144.
