The LCM of 168,189,831,572 is 59891832.
Find LCM of 168,189,831,572 with Prime Factorization
| 2 | 168, 189, 831, 572 |
| 2 | 84, 189, 831, 286 |
| 3 | 42, 189, 831, 143 |
| 7 | 14, 63, 277, 143 |
| 2, 9, 277, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 2 x 9 x 277 x 143 = 59891832
Therefore, the lowest common multiple of 168,189,831,572 is 59891832.
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 189 x 831 x 572 = 15092741664
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
189 : 1, 3, 7, 9, 21, 27, 63, 189
831 : 1, 3, 277, 831
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,189,831,572, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
189:3x 3x 3x 7
831:3x 277
572:2x 2x 11x 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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 15092741664/(1x252)
LCM = 15092741664/252
LCM = 59891832
Thus, we can understand that the LCM of 168,189,831,572 is 59891832.
