The LCM of 397,160,255,293,966 is 152817876960.
Find LCM of 397,160,255,293,966 with Prime Factorization
| 2 | 397, 160, 255, 293, 966 |
| 3 | 397, 80, 255, 293, 483 |
| 5 | 397, 80, 85, 293, 161 |
| 397, 16, 17, 293, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 397 x 16 x 17 x 293 x 161 = 152817876960
Therefore, the lowest common multiple of 397,160,255,293,966 is 152817876960.
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.
397 x 160 x 255 x 293 x 966 = 4584536308800
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.
397 : 1, 397
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
255 : 1, 3, 5, 15, 17, 51, 85, 255
293 : 1, 293
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,160,255,293,966, is 1.
Now, the common factors can be found like this.
397:397
160:2x 2x 2x 2x 2x 5
255:3x 5x 17
293:293
966:2x 3x 7x 23
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 5 = 30
Therefore, the value for common factors is 30.
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 = 4584536308800/(1x30)
LCM = 4584536308800/30
LCM = 152817876960
Thus, we can understand that the LCM of 397,160,255,293,966 is 152817876960.
