Find LCM of 261,279,978,736,696 with Prime Factorization
| 2 | 261, 279, 978, 736, 696 |
| 2 | 261, 279, 489, 368, 348 |
| 2 | 261, 279, 489, 184, 174 |
| 3 | 261, 279, 489, 92, 87 |
| 3 | 29, 93, 163, 92, 87 |
| 29 | 29, 31, 163, 92, 29 |
| 1, 31, 163, 92, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 29 x 1 x 31 x 163 x 92 x 1 = 970661088
Therefore, the lowest common multiple of 261,279,978,736,696 is 970661088.
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.
261 x 279 x 978 x 736 x 696 = 36481326331392
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.
261 : 1, 3, 9, 29, 87, 261
279 : 1, 3, 9, 31, 93, 279
978 : 1, 2, 3, 6, 163, 326, 489, 978
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,279,978,736,696, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
279:3x 3x 31
978:2x 3x 163
736:2x 2x 2x 2x 2x 23
696:2x 2x 2x 3x 29
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 3x 3x 3x 3x 29 = 37584
Therefore, the value for common factors is 37584.
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 = 36481326331392/(1x37584)
LCM = 36481326331392/37584
LCM = 970661088
Thus, we can understand that the LCM of 261,279,978,736,696 is 970661088.
