Given numbers are 197,894,745,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,894,745,189 is 55477170.
Find LCM of 197,894,745,189 with Prime Factorization
| 3 | 197, 894, 745, 189 |
| 149 | 197, 298, 745, 63 |
| 197, 2, 5, 63 |
Multiply the prime numbers at the bottom and the left side.
3 x 149 x 197 x 2 x 5 x 63 = 55477170
Therefore, the lowest common multiple of 197,894,745,189 is 55477170.
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.
197 x 894 x 745 x 189 = 24798294990
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.
197 : 1, 197
894 : 1, 2, 3, 6, 149, 298, 447, 894
745 : 1, 5, 149, 745
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,894,745,189, is 1.
Now, the common factors can be found like this.
197:197
894:2x 3x 149
745:5x 149
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 149 = 447
Therefore, the value for common factors is 447.
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 = 24798294990/(1x447)
LCM = 24798294990/447
LCM = 55477170
Thus, we can understand that the LCM of 197,894,745,189 is 55477170.
