Find LCM of 896,505,840,492 with Prime Factorization
| 2 | 896, 505, 840, 492 |
| 2 | 448, 505, 420, 246 |
| 2 | 224, 505, 210, 123 |
| 3 | 112, 505, 105, 123 |
| 5 | 112, 505, 35, 41 |
| 7 | 112, 101, 7, 41 |
| 16, 101, 1, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 16 x 101 x 1 x 41 = 55655040
Therefore, the lowest common multiple of 896,505,840,492 is 55655040.
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.
896 x 505 x 840 x 492 = 187000934400
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
505 : 1, 5, 101, 505
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,505,840,492, is 1.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
505:5x 101
840:2x 2x 2x 3x 5x 7
492:2x 2x 3x 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 3x 5x 7 = 3360
Therefore, the value for common factors is 3360.
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 = 187000934400/(1x3360)
LCM = 187000934400/3360
LCM = 55655040
Thus, we can understand that the LCM of 896,505,840,492 is 55655040.
