Find LCM of 395,381,952,945,144 with Prime Factorization
| 2 | 395, 381, 952, 945, 144 |
| 2 | 395, 381, 476, 945, 72 |
| 2 | 395, 381, 238, 945, 36 |
| 3 | 395, 381, 119, 945, 18 |
| 3 | 395, 127, 119, 315, 6 |

| 7 | 79, 127, 119, 21, 2 |
| 79, 127, 17, 3, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 7 x 79 x 127 x 17 x 3 x 2 = 2578882320
Therefore, the lowest common multiple of 395,381,952,945,144 is 2578882320.
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.
395 x 381 x 952 x 945 x 144 = 19496350339200
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.
395 : 1, 5, 79, 395
381 : 1, 3, 127, 381
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,381,952,945,144, is 1.
Now, the common factors can be found like this.
395:5x 79
381:3x 127
952:2x 2x 2x 7x 17
945:3x 3x 3x 5x 7
144:2x 2x 2x 2x 3x 3
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 5x 7 = 7560
Therefore, the value for common factors is 7560.
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 = 19496350339200/(1x7560)
LCM = 19496350339200/7560
LCM = 2578882320
Thus, we can understand that the LCM of 395,381,952,945,144 is 2578882320.
