The LCM of 400,218,551,160 is 48047200.
Find LCM of 400,218,551,160 with Prime Factorization
| 2 | 400, 218, 551, 160 |
| 2 | 200, 109, 551, 80 |
| 2 | 100, 109, 551, 40 |
| 2 | 50, 109, 551, 20 |
| 5 | 25, 109, 551, 10 |
| 5, 109, 551, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 5 x 109 x 551 x 2 = 48047200
Therefore, the lowest common multiple of 400,218,551,160 is 48047200.
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.
400 x 218 x 551 x 160 = 7687552000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
218 : 1, 2, 109, 218
551 : 1, 19, 29, 551
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,218,551,160, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
218:2x 109
551:19x 29
160:2x 2x 2x 2x 2x 5
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 5 = 160
Therefore, the value for common factors is 160.
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 = 7687552000/(1x160)
LCM = 7687552000/160
LCM = 48047200
Thus, we can understand that the LCM of 400,218,551,160 is 48047200.
