Find LCM of 218,144,646,488,109 with Prime Factorization
| 2 | 218, 144, 646, 488, 109 |
| 2 | 109, 72, 323, 244, 109 |
| 2 | 109, 36, 323, 122, 109 |
| 109 | 109, 18, 323, 61, 109 |
| 1, 18, 323, 61, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 109 x 1 x 18 x 323 x 61 x 1 = 309258288
Therefore, the lowest common multiple of 218,144,646,488,109 is 309258288.
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 144 x 646 x 488 x 109 = 1078692908544
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
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
646 : 1, 2, 17, 19, 34, 38, 323, 646
488 : 1, 2, 4, 8, 61, 122, 244, 488
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,144,646,488,109, is 1.
Now, the common factors can be found like this.
218:2x 109
144:2x 2x 2x 2x 3x 3
646:2x 17x 19
488:2x 2x 2x 61
109:109
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 109 = 3488
Therefore, the value for common factors is 3488.
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 = 1078692908544/(1x3488)
LCM = 1078692908544/3488
LCM = 309258288
Thus, we can understand that the LCM of 218,144,646,488,109 is 309258288.
