The LCM of 544,505,988,680 is 67855840.
Find LCM of 544,505,988,680 with Prime Factorization
| 2 | 544, 505, 988, 680 |
| 2 | 272, 505, 494, 340 |
| 2 | 136, 505, 247, 170 |
| 5 | 68, 505, 247, 85 |
| 17 | 68, 101, 247, 17 |
| 4, 101, 247, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 4 x 101 x 247 x 1 = 67855840
Therefore, the lowest common multiple of 544,505,988,680 is 67855840.
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.
544 x 505 x 988 x 680 = 184567884800
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.
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
505 : 1, 5, 101, 505
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 544,505,988,680, is 1.
Now, the common factors can be found like this.
544:2x 2x 2x 2x 2x 17
505:5x 101
988:2x 2x 13x 19
680:2x 2x 2x 5x 17
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 5x 17 = 2720
Therefore, the value for common factors is 2720.
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 = 184567884800/(1x2720)
LCM = 184567884800/2720
LCM = 67855840
Thus, we can understand that the LCM of 544,505,988,680 is 67855840.
