Given numbers are 168,974,964,181
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 168,974,964,181 is 3568895736.
Find LCM of 168,974,964,181 with Prime Factorization
| 2 | 168, 974, 964, 181 |
| 2 | 84, 487, 482, 181 |
| 42, 487, 241, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 42 x 487 x 241 x 181 = 3568895736
Therefore, the lowest common multiple of 168,974,964,181 is 3568895736.
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 974 x 964 x 181 = 28551165888
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
974 : 1, 2, 487, 974
964 : 1, 2, 4, 241, 482, 964
181 : 1, 181
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,974,964,181, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
974:2x 487
964:2x 2x 241
181:181
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 2 = 8
Therefore, the value for common factors is 8.
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 = 28551165888/(1x8)
LCM = 28551165888/8
LCM = 3568895736
Thus, we can understand that the LCM of 168,974,964,181 is 3568895736.
