Find LCM of 868,112,238,896 with Prime Factorization
| 2 | 868, 112, 238, 896 |
| 2 | 434, 56, 119, 448 |
| 2 | 217, 28, 119, 224 |
| 2 | 217, 14, 119, 112 |
| 7 | 217, 7, 119, 56 |
| 31, 1, 17, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 31 x 1 x 17 x 8 = 472192
Therefore, the lowest common multiple of 868,112,238,896 is 472192.
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.
868 x 112 x 238 x 896 = 20731117568
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
238 : 1, 2, 7, 14, 17, 34, 119, 238
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
14 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,112,238,896, is 14.
Now, the common factors can be found like this.
868:2x 2x 7x 31
112:2x 2x 2x 2x 7
238:2x 7x 17
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 7x 7 = 3136
Therefore, the value for common factors is 3136.
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 = 20731117568/(14x3136)
LCM = 20731117568/43904
LCM = 472192
Thus, we can understand that the LCM of 868,112,238,896 is 472192.
