Given numbers are 165,548,620,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,548,620,913 is 232650660.
Find LCM of 165,548,620,913 with Prime Factorization
| 2 | 165, 548, 620, 913 |
| 2 | 165, 274, 310, 913 |
| 5 | 165, 137, 155, 913 |
| 11 | 33, 137, 31, 913 |
| 3, 137, 31, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 3 x 137 x 31 x 83 = 232650660
Therefore, the lowest common multiple of 165,548,620,913 is 232650660.
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.
165 x 548 x 620 x 913 = 51183145200
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
548 : 1, 2, 4, 137, 274, 548
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,548,620,913, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
548:2x 2x 137
620:2x 2x 5x 31
913:11x 83
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 51183145200/(1x220)
LCM = 51183145200/220
LCM = 232650660
Thus, we can understand that the LCM of 165,548,620,913 is 232650660.
