Given numbers are 431,646,459,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,646,459,697 is 308217582.
Find LCM of 431,646,459,697 with Prime Factorization
| 17 | 431, 646, 459, 697 |
| 431, 38, 27, 41 |
Multiply the prime numbers at the bottom and the left side.
17 x 431 x 38 x 27 x 41 = 308217582
Therefore, the lowest common multiple of 431,646,459,697 is 308217582.
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.
431 x 646 x 459 x 697 = 89074881198
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.
431 : 1, 431
646 : 1, 2, 17, 19, 34, 38, 323, 646
459 : 1, 3, 9, 17, 27, 51, 153, 459
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,646,459,697, is 1.
Now, the common factors can be found like this.
431:431
646:2x 17x 19
459:3x 3x 3x 17
697:17x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 17 = 289
Therefore, the value for common factors is 289.
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 = 89074881198/(1x289)
LCM = 89074881198/289
LCM = 308217582
Thus, we can understand that the LCM of 431,646,459,697 is 308217582.
