Find LCM of 987,860,273,423,169 with Prime Factorization
| 3 | 987, 860, 273, 423, 169 |
| 7 | 329, 860, 91, 141, 169 |
| 13 | 47, 860, 13, 141, 169 |
| 47 | 47, 860, 1, 141, 13 |
| 1, 860, 1, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 47 x 1 x 860 x 1 x 3 x 13 = 430351740
Therefore, the lowest common multiple of 987,860,273,423,169 is 430351740.
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.
987 x 860 x 273 x 423 x 169 = 16565529527820
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
273 : 1, 3, 7, 13, 21, 39, 91, 273
423 : 1, 3, 9, 47, 141, 423
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,860,273,423,169, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
860:2x 2x 5x 43
273:3x 7x 13
423:3x 3x 47
169:13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 13x 47 = 38493
Therefore, the value for common factors is 38493.
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 = 16565529527820/(1x38493)
LCM = 16565529527820/38493
LCM = 430351740
Thus, we can understand that the LCM of 987,860,273,423,169 is 430351740.
