The LCM of 189,648,503,658 is 107235576.
Find LCM of 189,648,503,658 with Prime Factorization
| 2 | 189, 648, 503, 658 |
| 3 | 189, 324, 503, 329 |
| 3 | 63, 108, 503, 329 |
| 3 | 21, 36, 503, 329 |
| 7 | 7, 12, 503, 329 |
| 1, 12, 503, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 1 x 12 x 503 x 47 = 107235576
Therefore, the lowest common multiple of 189,648,503,658 is 107235576.
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.
189 x 648 x 503 x 658 = 40535047728
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
503 : 1, 503
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,648,503,658, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
648:2x 2x 2x 3x 3x 3x 3
503:503
658:2x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 40535047728/(1x378)
LCM = 40535047728/378
LCM = 107235576
Thus, we can understand that the LCM of 189,648,503,658 is 107235576.
