Given numbers are 636,789,460,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,789,460,828 is 57707460.
Find LCM of 636,789,460,828 with Prime Factorization
| 2 | 636, 789, 460, 828 |
| 2 | 318, 789, 230, 414 |
| 3 | 159, 789, 115, 207 |
| 23 | 53, 263, 115, 69 |
| 53, 263, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 53 x 263 x 5 x 3 = 57707460
Therefore, the lowest common multiple of 636,789,460,828 is 57707460.
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 789 x 460 x 828 = 191127107520
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
789 : 1, 3, 263, 789
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,789,460,828, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
789:3x 263
460:2x 2x 5x 23
828:2x 2x 3x 3x 23
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 23 = 3312
Therefore, the value for common factors is 3312.
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 = 191127107520/(1x3312)
LCM = 191127107520/3312
LCM = 57707460
Thus, we can understand that the LCM of 636,789,460,828 is 57707460.
