Find LCM of 178,440,781,219,960 with Prime Factorization
| 2 | 178, 440, 781, 219, 960 |
| 2 | 89, 220, 781, 219, 480 |
| 2 | 89, 110, 781, 219, 240 |
| 3 | 89, 55, 781, 219, 120 |
| 5 | 89, 55, 781, 73, 40 |
| 11 | 89, 11, 781, 73, 8 |
| 89, 1, 71, 73, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 11 x 89 x 1 x 71 x 73 x 8 = 4871190720
Therefore, the lowest common multiple of 178,440,781,219,960 is 4871190720.
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.
178 x 440 x 781 x 219 x 960 = 12859943500800
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.
178 : 1, 2, 89, 178
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
781 : 1, 11, 71, 781
219 : 1, 3, 73, 219
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,440,781,219,960, is 1.
Now, the common factors can be found like this.
178:2x 89
440:2x 2x 2x 5x 11
781:11x 71
219:3x 73
960:2x 2x 2x 2x 2x 2x 3x 5
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 5x 11 = 2640
Therefore, the value for common factors is 2640.
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 = 12859943500800/(1x2640)
LCM = 12859943500800/2640
LCM = 4871190720
Thus, we can understand that the LCM of 178,440,781,219,960 is 4871190720.
