Find LCM of 990,545,216,393,676 with Prime Factorization
| 2 | 990, 545, 216, 393, 676 |
| 2 | 495, 545, 108, 393, 338 |
| 3 | 495, 545, 54, 393, 169 |
| 3 | 165, 545, 18, 131, 169 |
| 5 | 55, 545, 6, 131, 169 |
| 11, 109, 6, 131, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 11 x 109 x 6 x 131 x 169 = 28668233880
Therefore, the lowest common multiple of 990,545,216,393,676 is 28668233880.
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.
990 x 545 x 216 x 393 x 676 = 30961692590400
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.
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
545 : 1, 5, 109, 545
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
393 : 1, 3, 131, 393
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,545,216,393,676, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
545:5x 109
216:2x 2x 2x 3x 3x 3
393:3x 131
676:2x 2x 13x 13
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 5 = 1080
Therefore, the value for common factors is 1080.
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 = 30961692590400/(1x1080)
LCM = 30961692590400/1080
LCM = 28668233880
Thus, we can understand that the LCM of 990,545,216,393,676 is 28668233880.
