Find LCM of 679,840,696,428,664 with Prime Factorization
| 2 | 679, 840, 696, 428, 664 |
| 2 | 679, 420, 348, 214, 332 |
| 2 | 679, 210, 174, 107, 166 |
| 3 | 679, 105, 87, 107, 83 |
| 7 | 679, 35, 29, 107, 83 |
| 97, 5, 29, 107, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 97 x 5 x 29 x 107 x 83 = 20985092520
Therefore, the lowest common multiple of 679,840,696,428,664 is 20985092520.
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.
679 x 840 x 696 x 428 x 664 = 112815857387520
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.
679 : 1, 7, 97, 679
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
428 : 1, 2, 4, 107, 214, 428
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,840,696,428,664, is 1.
Now, the common factors can be found like this.
679:7x 97
840:2x 2x 2x 3x 5x 7
696:2x 2x 2x 3x 29
428:2x 2x 107
664:2x 2x 2x 83
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 2x 2x 2x 3x 7 = 5376
Therefore, the value for common factors is 5376.
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 = 112815857387520/(1x5376)
LCM = 112815857387520/5376
LCM = 20985092520
Thus, we can understand that the LCM of 679,840,696,428,664 is 20985092520.
