The LCM of 305,861,917,961,735 is 231417242385.
Find LCM of 305,861,917,961,735 with Prime Factorization
| 3 | 305, 861, 917, 961, 735 |
| 5 | 305, 287, 917, 961, 245 |
| 7 | 61, 287, 917, 961, 49 |
| 61, 41, 131, 961, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 61 x 41 x 131 x 961 x 7 = 231417242385
Therefore, the lowest common multiple of 305,861,917,961,735 is 231417242385.
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.
305 x 861 x 917 x 961 x 735 = 170091673152975
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.
305 : 1, 5, 61, 305
861 : 1, 3, 7, 21, 41, 123, 287, 861
917 : 1, 7, 131, 917
961 : 1, 31, 961
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,861,917,961,735, is 1.
Now, the common factors can be found like this.
305:5x 61
861:3x 7x 41
917:7x 131
961:31x 31
735:3x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 7 = 735
Therefore, the value for common factors is 735.
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 = 170091673152975/(1x735)
LCM = 170091673152975/735
LCM = 231417242385
Thus, we can understand that the LCM of 305,861,917,961,735 is 231417242385.
