Find LCM of 484,254,144,561 with Prime Factorization
| 2 | 484, 254, 144, 561 |
| 2 | 242, 127, 72, 561 |
| 3 | 121, 127, 36, 561 |
| 11 | 121, 127, 12, 187 |
| 11, 127, 12, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 11 x 127 x 12 x 17 = 37618416
Therefore, the lowest common multiple of 484,254,144,561 is 37618416.
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.
484 x 254 x 144 x 561 = 9931261824
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
254 : 1, 2, 127, 254
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,254,144,561, is 1.
Now, the common factors can be found like this.
484:2x 2x 11x 11
254:2x 127
144:2x 2x 2x 2x 3x 3
561:3x 11x 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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 9931261824/(1x264)
LCM = 9931261824/264
LCM = 37618416
Thus, we can understand that the LCM of 484,254,144,561 is 37618416.
