Find LCM of 218,545,788,959,868 with Prime Factorization
| 2 | 218, 545, 788, 959, 868 |
| 2 | 109, 545, 394, 959, 434 |
| 7 | 109, 545, 197, 959, 217 |
| 109 | 109, 545, 197, 137, 31 |
| 1, 5, 197, 137, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 109 x 1 x 5 x 197 x 137 x 31 = 12767416340
Therefore, the lowest common multiple of 218,545,788,959,868 is 12767416340.
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.
218 x 545 x 788 x 959 x 868 = 77932309339360
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.
218 : 1, 2, 109, 218
545 : 1, 5, 109, 545
788 : 1, 2, 4, 197, 394, 788
959 : 1, 7, 137, 959
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,545,788,959,868, is 1.
Now, the common factors can be found like this.
218:2x 109
545:5x 109
788:2x 2x 197
959:7x 137
868:2x 2x 7x 31
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 7x 109 = 6104
Therefore, the value for common factors is 6104.
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 = 77932309339360/(1x6104)
LCM = 77932309339360/6104
LCM = 12767416340
Thus, we can understand that the LCM of 218,545,788,959,868 is 12767416340.
