Find LCM of 945,880,554,794,560 with Prime Factorization
| 2 | 945, 880, 554, 794, 560 |
| 2 | 945, 440, 277, 397, 280 |
| 2 | 945, 220, 277, 397, 140 |
| 2 | 945, 110, 277, 397, 70 |
| 5 | 945, 55, 277, 397, 35 |
| 7 | 189, 11, 277, 397, 7 |
| 27, 11, 277, 397, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 7 x 27 x 11 x 277 x 397 x 1 = 18290044080
Therefore, the lowest common multiple of 945,880,554,794,560 is 18290044080.
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.
945 x 880 x 554 x 794 x 560 = 204848493696000
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
554 : 1, 2, 277, 554
794 : 1, 2, 397, 794
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,880,554,794,560, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
880:2x 2x 2x 2x 5x 11
554:2x 277
794:2x 397
560:2x 2x 2x 2x 5x 7
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 5x 5x 7 = 11200
Therefore, the value for common factors is 11200.
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 = 204848493696000/(1x11200)
LCM = 204848493696000/11200
LCM = 18290044080
Thus, we can understand that the LCM of 945,880,554,794,560 is 18290044080.
