Given numbers are 636,380,684,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,380,684,129 is 7794180.
Find LCM of 636,380,684,129 with Prime Factorization
| 2 | 636, 380, 684, 129 |
| 2 | 318, 190, 342, 129 |
| 3 | 159, 95, 171, 129 |
| 19 | 53, 95, 57, 43 |
| 53, 5, 3, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 53 x 5 x 3 x 43 = 7794180
Therefore, the lowest common multiple of 636,380,684,129 is 7794180.
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.
636 x 380 x 684 x 129 = 21324876480
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,380,684,129, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
380:2x 2x 5x 19
684:2x 2x 3x 3x 19
129:3x 43
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 2x 2x 3x 3x 19 = 2736
Therefore, the value for common factors is 2736.
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 = 21324876480/(1x2736)
LCM = 21324876480/2736
LCM = 7794180
Thus, we can understand that the LCM of 636,380,684,129 is 7794180.
