Given numbers are 661,867,661,833
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,867,661,833 is 28081263.
Find LCM of 661,867,661,833 with Prime Factorization
| 17 | 661, 867, 661, 833 |
| 661 | 661, 51, 661, 49 |
| 1, 51, 1, 49 |
Multiply the prime numbers at the bottom and the left side.
17 x 661 x 1 x 51 x 1 x 49 = 28081263
Therefore, the lowest common multiple of 661,867,661,833 is 28081263.
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.
661 x 867 x 661 x 833 = 315549152331
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.
661 : 1, 661
867 : 1, 3, 17, 51, 289, 867
661 : 1, 661
833 : 1, 7, 17, 49, 119, 833
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,867,661,833, is 1.
Now, the common factors can be found like this.
661:661
867:3x 17x 17
661:661
833:7x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 661 = 11237
Therefore, the value for common factors is 11237.
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 = 315549152331/(1x11237)
LCM = 315549152331/11237
LCM = 28081263
Thus, we can understand that the LCM of 661,867,661,833 is 28081263.
