Find LCM of 390,732,171,915,127 with Prime Factorization
| 2 | 390, 732, 171, 915, 127 |
| 3 | 195, 366, 171, 915, 127 |
| 5 | 65, 122, 57, 305, 127 |
| 61 | 13, 122, 57, 61, 127 |
| 13, 2, 57, 1, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 61 x 13 x 2 x 57 x 1 x 127 = 344431620
Therefore, the lowest common multiple of 390,732,171,915,127 is 344431620.
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.
390 x 732 x 171 x 915 x 127 = 5672788781400
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
171 : 1, 3, 9, 19, 57, 171
915 : 1, 3, 5, 15, 61, 183, 305, 915
127 : 1, 127
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,732,171,915,127, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
732:2x 2x 3x 61
171:3x 3x 19
915:3x 5x 61
127:127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 61 = 16470
Therefore, the value for common factors is 16470.
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 = 5672788781400/(1x16470)
LCM = 5672788781400/16470
LCM = 344431620
Thus, we can understand that the LCM of 390,732,171,915,127 is 344431620.
