Find LCM of 168,728,624,131,828 with Prime Factorization
| 2 | 168, 728, 624, 131, 828 |
| 2 | 84, 364, 312, 131, 414 |
| 2 | 42, 182, 156, 131, 207 |
| 3 | 21, 91, 78, 131, 207 |
| 7 | 7, 91, 26, 131, 69 |
| 13 | 1, 13, 26, 131, 69 |
| 1, 1, 2, 131, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 1 x 1 x 2 x 131 x 69 = 39482352
Therefore, the lowest common multiple of 168,728,624,131,828 is 39482352.
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.
168 x 728 x 624 x 131 x 828 = 8278027849728
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
131 : 1, 131
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,728,624,131,828, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
728:2x 2x 2x 7x 13
624:2x 2x 2x 2x 3x 13
131:131
828:2x 2x 3x 3x 23
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 2x 2x 2x 3x 3x 7x 13 = 209664
Therefore, the value for common factors is 209664.
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 = 8278027849728/(1x209664)
LCM = 8278027849728/209664
LCM = 39482352
Thus, we can understand that the LCM of 168,728,624,131,828 is 39482352.
