Given numbers are 791,481,315,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,481,315,781 is 13371653295.
Find LCM of 791,481,315,781 with Prime Factorization
| 7 | 791, 481, 315, 781 |
| 113, 481, 45, 781 |
Multiply the prime numbers at the bottom and the left side.
7 x 113 x 481 x 45 x 781 = 13371653295
Therefore, the lowest common multiple of 791,481,315,781 is 13371653295.
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.
791 x 481 x 315 x 781 = 93601573065
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.
791 : 1, 7, 113, 791
481 : 1, 13, 37, 481
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,481,315,781, is 1.
Now, the common factors can be found like this.
791:7x 113
481:13x 37
315:3x 3x 5x 7
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 93601573065/(1x7)
LCM = 93601573065/7
LCM = 13371653295
Thus, we can understand that the LCM of 791,481,315,781 is 13371653295.
