Find LCM of 665,638,472,880,960 with Prime Factorization
| 2 | 665, 638, 472, 880, 960 |
| 2 | 665, 319, 236, 440, 480 |
| 2 | 665, 319, 118, 220, 240 |
| 2 | 665, 319, 59, 110, 120 |
| 5 | 665, 319, 59, 55, 60 |
| 11 | 133, 319, 59, 11, 12 |
| 133, 29, 59, 1, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 11 x 133 x 29 x 59 x 1 x 12 = 2403065280
Therefore, the lowest common multiple of 665,638,472,880,960 is 2403065280.
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.
665 x 638 x 472 x 880 x 960 = 169175795712000
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
638 : 1, 2, 11, 22, 29, 58, 319, 638
472 : 1, 2, 4, 8, 59, 118, 236, 472
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
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 665,638,472,880,960, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
638:2x 11x 29
472:2x 2x 2x 59
880:2x 2x 2x 2x 5x 11
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 2x 2x 2x 2x 5x 5x 11 = 70400
Therefore, the value for common factors is 70400.
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 = 169175795712000/(1x70400)
LCM = 169175795712000/70400
LCM = 2403065280
Thus, we can understand that the LCM of 665,638,472,880,960 is 2403065280.
