Find LCM of 306,180,387,946,917 with Prime Factorization
2 | 306, 180, 387, 946, 917 |
3 | 153, 90, 387, 473, 917 |
3 | 51, 30, 129, 473, 917 |
43 | 17, 10, 43, 473, 917 |
17, 10, 1, 11, 917 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 43 x 17 x 10 x 1 x 11 x 917 = 1327247460
Therefore, the lowest common multiple of 306,180,387,946,917 is 1327247460.
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.
306 x 180 x 387 x 946 x 917 = 18491211612720
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.
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
387 : 1, 3, 9, 43, 129, 387
946 : 1, 2, 11, 22, 43, 86, 473, 946
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,180,387,946,917, is 1.
Now, the common factors can be found like this.
306:2x 3x 3x 17
180:2x 2x 3x 3x 5
387:3x 3x 43
946:2x 11x 43
917:7x 131
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 3x 3x 3x 3x 43 = 13932
Therefore, the value for common factors is 13932.
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 = 18491211612720/(1x13932)
LCM = 18491211612720/13932
LCM = 1327247460
Thus, we can understand that the LCM of 306,180,387,946,917 is 1327247460.
