The LCM of 665,876,590,612,621 is 120947537340.
Find LCM of 665,876,590,612,621 with Prime Factorization
| 2 | 665, 876, 590, 612, 621 |
| 2 | 665, 438, 295, 306, 621 |
| 3 | 665, 219, 295, 153, 621 |
| 3 | 665, 73, 295, 51, 207 |
| 5 | 665, 73, 295, 17, 69 |
| 133, 73, 59, 17, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 133 x 73 x 59 x 17 x 69 = 120947537340
Therefore, the lowest common multiple of 665,876,590,612,621 is 120947537340.
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.
665 x 876 x 590 x 612 x 621 = 130623340327200
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
590 : 1, 2, 5, 10, 59, 118, 295, 590
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,876,590,612,621, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
876:2x 2x 3x 73
590:2x 5x 59
612:2x 2x 3x 3x 17
621:3x 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 3x 3x 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 130623340327200/(1x1080)
LCM = 130623340327200/1080
LCM = 120947537340
Thus, we can understand that the LCM of 665,876,590,612,621 is 120947537340.
