Given numbers are 660,253,672,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 660,253,672,717 is 203169120.
Find LCM of 660,253,672,717 with Prime Factorization
| 2 | 660, 253, 672, 717 |
| 2 | 330, 253, 336, 717 |
| 3 | 165, 253, 168, 717 |
| 11 | 55, 253, 56, 239 |
| 5, 23, 56, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 5 x 23 x 56 x 239 = 203169120
Therefore, the lowest common multiple of 660,253,672,717 is 203169120.
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.
660 x 253 x 672 x 717 = 80454971520
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
253 : 1, 11, 23, 253
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,253,672,717, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
253:11x 23
672:2x 2x 2x 2x 2x 3x 7
717:3x 239
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 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 80454971520/(1x396)
LCM = 80454971520/396
LCM = 203169120
Thus, we can understand that the LCM of 660,253,672,717 is 203169120.
