Given numbers are 403,813,702,465
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,813,702,465 is 29487510.
Find LCM of 403,813,702,465 with Prime Factorization
| 3 | 403, 813, 702, 465 |
| 13 | 403, 271, 234, 155 |
| 31 | 31, 271, 18, 155 |
| 1, 271, 18, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 31 x 1 x 271 x 18 x 5 = 29487510
Therefore, the lowest common multiple of 403,813,702,465 is 29487510.
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.
403 x 813 x 702 x 465 = 106951198770
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.
403 : 1, 13, 31, 403
813 : 1, 3, 271, 813
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
465 : 1, 3, 5, 15, 31, 93, 155, 465
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,813,702,465, is 1.
Now, the common factors can be found like this.
403:13x 31
813:3x 271
702:2x 3x 3x 3x 13
465:3x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 31 = 3627
Therefore, the value for common factors is 3627.
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 = 106951198770/(1x3627)
LCM = 106951198770/3627
LCM = 29487510
Thus, we can understand that the LCM of 403,813,702,465 is 29487510.
