The LCM of 900,693,640,330 is 2217600.
Find LCM of 900,693,640,330 with Prime Factorization
| 2 | 900, 693, 640, 330 |
| 2 | 450, 693, 320, 165 |
| 3 | 225, 693, 160, 165 |
| 3 | 75, 231, 160, 55 |
| 5 | 25, 77, 160, 55 |
| 11 | 5, 77, 32, 11 |
| 5, 7, 32, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 11 x 5 x 7 x 32 x 1 = 2217600
Therefore, the lowest common multiple of 900,693,640,330 is 2217600.
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.
900 x 693 x 640 x 330 = 131725440000
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.
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,693,640,330, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
693:3x 3x 7x 11
640:2x 2x 2x 2x 2x 2x 2x 5
330:2x 3x 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 3x 3x 3x 5x 5x 11 = 59400
Therefore, the value for common factors is 59400.
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 = 131725440000/(1x59400)
LCM = 131725440000/59400
LCM = 2217600
Thus, we can understand that the LCM of 900,693,640,330 is 2217600.
