Find LCM of 678,140,696,124,880 with Prime Factorization
| 2 | 678, 140, 696, 124, 880 |
| 2 | 339, 70, 348, 62, 440 |
| 2 | 339, 35, 174, 31, 220 |
| 3 | 339, 35, 87, 31, 110 |
| 5 | 113, 35, 29, 31, 110 |
| 113, 7, 29, 31, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 113 x 7 x 29 x 31 x 22 = 1877327760
Therefore, the lowest common multiple of 678,140,696,124,880 is 1877327760.
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.
678 x 140 x 696 x 124 x 880 = 7208938598400
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
124 : 1, 2, 4, 31, 62, 124
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,140,696,124,880, is 2.
Now, the common factors can be found like this.
678:2x 3x 113
140:2x 2x 5x 7
696:2x 2x 2x 3x 29
124:2x 2x 31
880:2x 2x 2x 2x 5x 11
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 3x 5 = 1920
Therefore, the value for common factors is 1920.
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 = 7208938598400/(2x1920)
LCM = 7208938598400/3840
LCM = 1877327760
Thus, we can understand that the LCM of 678,140,696,124,880 is 1877327760.
