Find LCM of 138,487,989,756,329 with Prime Factorization
| 2 | 138, 487, 989, 756, 329 |
| 3 | 69, 487, 989, 378, 329 |
| 7 | 23, 487, 989, 126, 329 |
| 23 | 23, 487, 989, 18, 47 |
| 1, 487, 43, 18, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 1 x 487 x 43 x 18 x 47 = 17113739076
Therefore, the lowest common multiple of 138,487,989,756,329 is 17113739076.
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.
138 x 487 x 989 x 756 x 329 = 16531871947416
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
487 : 1, 487
989 : 1, 23, 43, 989
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
329 : 1, 7, 47, 329
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,487,989,756,329, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
487:487
989:23x 43
756:2x 2x 3x 3x 3x 7
329:7x 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 7x 23 = 966
Therefore, the value for common factors is 966.
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 = 16531871947416/(1x966)
LCM = 16531871947416/966
LCM = 17113739076
Thus, we can understand that the LCM of 138,487,989,756,329 is 17113739076.
