Find LCM of 242,488,778,747,664 with Prime Factorization
| 2 | 242, 488, 778, 747, 664 |
| 2 | 121, 244, 389, 747, 332 |
| 2 | 121, 122, 389, 747, 166 |
| 83 | 121, 61, 389, 747, 83 |
| 121, 61, 389, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 83 x 121 x 61 x 389 x 9 x 1 = 17158344984
Therefore, the lowest common multiple of 242,488,778,747,664 is 17158344984.
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 488 x 778 x 747 x 664 = 45572564277504
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
488 : 1, 2, 4, 8, 61, 122, 244, 488
778 : 1, 2, 389, 778
747 : 1, 3, 9, 83, 249, 747
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,488,778,747,664, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
488:2x 2x 2x 61
778:2x 389
747:3x 3x 83
664:2x 2x 2x 83
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 2x 2x 83 = 2656
Therefore, the value for common factors is 2656.
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 = 45572564277504/(1x2656)
LCM = 45572564277504/2656
LCM = 17158344984
Thus, we can understand that the LCM of 242,488,778,747,664 is 17158344984.
