The LCM of 188,661,168,987 is 5219256.
Find LCM of 188,661,168,987 with Prime Factorization
| 2 | 188, 661, 168, 987 |
| 2 | 94, 661, 84, 987 |
| 3 | 47, 661, 42, 987 |
| 7 | 47, 661, 14, 329 |
| 47 | 47, 661, 2, 47 |
| 1, 661, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 47 x 1 x 661 x 2 x 1 = 5219256
Therefore, the lowest common multiple of 188,661,168,987 is 5219256.
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.
188 x 661 x 168 x 987 = 20605622688
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.
188 : 1, 2, 4, 47, 94, 188
661 : 1, 661
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,661,168,987, is 1.
Now, the common factors can be found like this.
188:2x 2x 47
661:661
168:2x 2x 2x 3x 7
987:3x 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 2x 3x 7x 47 = 3948
Therefore, the value for common factors is 3948.
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 = 20605622688/(1x3948)
LCM = 20605622688/3948
LCM = 5219256
Thus, we can understand that the LCM of 188,661,168,987 is 5219256.
