Given numbers are 394,756,683,871,910
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 394,756,683,871,910 is 442993021380.
Find LCM of 394,756,683,871,910 with Prime Factorization
| 2 | 394, 756, 683, 871, 910 |
| 7 | 197, 378, 683, 871, 455 |
| 13 | 197, 54, 683, 871, 65 |
| 197, 54, 683, 67, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 197 x 54 x 683 x 67 x 5 = 442993021380
Therefore, the lowest common multiple of 394,756,683,871,910 is 442993021380.
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.
394 x 756 x 683 x 871 x 910 = 161249459782320
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.
394 : 1, 2, 197, 394
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
683 : 1, 683
871 : 1, 13, 67, 871
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,756,683,871,910, is 1.
Now, the common factors can be found like this.
394:2x 197
756:2x 2x 3x 3x 3x 7
683:683
871:13x 67
910:2x 5x 7x 13
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 7x 13 = 364
Therefore, the value for common factors is 364.
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 = 161249459782320/(1x364)
LCM = 161249459782320/364
LCM = 442993021380
Thus, we can understand that the LCM of 394,756,683,871,910 is 442993021380.
