The LCM of 551,141,747,855 is 96725295.
Find LCM of 551,141,747,855 with Prime Factorization
| 3 | 551, 141, 747, 855 |
| 3 | 551, 47, 249, 285 |
| 19 | 551, 47, 83, 95 |
| 29, 47, 83, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 29 x 47 x 83 x 5 = 96725295
Therefore, the lowest common multiple of 551,141,747,855 is 96725295.
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.
551 x 141 x 747 x 855 = 49620076335
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.
551 : 1, 19, 29, 551
141 : 1, 3, 47, 141
747 : 1, 3, 9, 83, 249, 747
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,141,747,855, is 1.
Now, the common factors can be found like this.
551:19x 29
141:3x 47
747:3x 3x 83
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 19 = 513
Therefore, the value for common factors is 513.
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 = 49620076335/(1x513)
LCM = 49620076335/513
LCM = 96725295
Thus, we can understand that the LCM of 551,141,747,855 is 96725295.
