Find LCM of 138,468,225,684,520 with Prime Factorization
2 | 138, 468, 225, 684, 520 |
2 | 69, 234, 225, 342, 260 |
3 | 69, 117, 225, 171, 130 |
3 | 23, 39, 75, 57, 130 |
5 | 23, 13, 25, 19, 130 |
13 | 23, 13, 5, 19, 26 |
23, 1, 5, 19, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 13 x 23 x 1 x 5 x 19 x 2 = 10225800
Therefore, the lowest common multiple of 138,468,225,684,520 is 10225800.
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 468 x 225 x 684 x 520 = 5168528352000
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
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,468,225,684,520, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
468:2x 2x 3x 3x 13
225:3x 3x 5x 5
684:2x 2x 3x 3x 19
520:2x 2x 2x 5x 13
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 3x 3x 3x 3x 3x 5x 13 = 505440
Therefore, the value for common factors is 505440.
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 = 5168528352000/(1x505440)
LCM = 5168528352000/505440
LCM = 10225800
Thus, we can understand that the LCM of 138,468,225,684,520 is 10225800.
