Find LCM of 311,640,453,836,684 with Prime Factorization
| 2 | 311, 640, 453, 836, 684 |
| 2 | 311, 320, 453, 418, 342 |
| 3 | 311, 160, 453, 209, 171 |
| 19 | 311, 160, 151, 209, 57 |
| 311, 160, 151, 11, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 311 x 160 x 151 x 11 x 3 = 56533530240
Therefore, the lowest common multiple of 311,640,453,836,684 is 56533530240.
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.
311 x 640 x 453 x 836 x 684 = 51558579578880
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.
311 : 1, 311
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
453 : 1, 3, 151, 453
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,640,453,836,684, is 1.
Now, the common factors can be found like this.
311:311
640:2x 2x 2x 2x 2x 2x 2x 5
453:3x 151
836:2x 2x 11x 19
684:2x 2x 3x 3x 19
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 19 = 912
Therefore, the value for common factors is 912.
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 = 51558579578880/(1x912)
LCM = 51558579578880/912
LCM = 56533530240
Thus, we can understand that the LCM of 311,640,453,836,684 is 56533530240.
