The LCM of 495,812,640,999 is 1427690880.
Find LCM of 495,812,640,999 with Prime Factorization
| 2 | 495, 812, 640, 999 |
| 2 | 495, 406, 320, 999 |
| 3 | 495, 203, 160, 999 |
| 3 | 165, 203, 160, 333 |
| 5 | 55, 203, 160, 111 |
| 11, 203, 32, 111 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 11 x 203 x 32 x 111 = 1427690880
Therefore, the lowest common multiple of 495,812,640,999 is 1427690880.
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.
495 x 812 x 640 x 999 = 256984358400
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,812,640,999, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
812:2x 2x 7x 29
640:2x 2x 2x 2x 2x 2x 2x 5
999:3x 3x 3x 37
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 256984358400/(1x180)
LCM = 256984358400/180
LCM = 1427690880
Thus, we can understand that the LCM of 495,812,640,999 is 1427690880.
