The LCM of 892,189,984,768 is 442374912.
Find LCM of 892,189,984,768 with Prime Factorization
| 2 | 892, 189, 984, 768 |
| 2 | 446, 189, 492, 384 |
| 2 | 223, 189, 246, 192 |
| 3 | 223, 189, 123, 96 |
| 223, 63, 41, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 223 x 63 x 41 x 32 = 442374912
Therefore, the lowest common multiple of 892,189,984,768 is 442374912.
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.
892 x 189 x 984 x 768 = 127403974656
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.
892 : 1, 2, 4, 223, 446, 892
189 : 1, 3, 7, 9, 21, 27, 63, 189
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,189,984,768, is 1.
Now, the common factors can be found like this.
892:2x 2x 223
189:3x 3x 3x 7
984:2x 2x 2x 3x 41
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 3 = 288
Therefore, the value for common factors is 288.
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 = 127403974656/(1x288)
LCM = 127403974656/288
LCM = 442374912
Thus, we can understand that the LCM of 892,189,984,768 is 442374912.
