Given numbers are 242,781,497,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 242,781,497,717 is 86236458.
Find LCM of 242,781,497,717 with Prime Factorization
| 11 | 242, 781, 497, 717 |
| 71 | 22, 71, 497, 717 |
| 22, 1, 7, 717 |
Multiply the prime numbers at the bottom and the left side.
11 x 71 x 22 x 1 x 7 x 717 = 86236458
Therefore, the lowest common multiple of 242,781,497,717 is 86236458.
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.
242 x 781 x 497 x 717 = 67350673698
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.
242 : 1, 2, 11, 22, 121, 242
781 : 1, 11, 71, 781
497 : 1, 7, 71, 497
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,781,497,717, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
781:11x 71
497:7x 71
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.
11x 71 = 781
Therefore, the value for common factors is 781.
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 = 67350673698/(1x781)
LCM = 67350673698/781
LCM = 86236458
Thus, we can understand that the LCM of 242,781,497,717 is 86236458.
