The LCM of 197,985,154,385 is 151690.
Find LCM of 197,985,154,385 with Prime Factorization
| 5 | 197, 985, 154, 385 |
| 7 | 197, 197, 154, 77 |
| 11 | 197, 197, 22, 11 |
| 197 | 197, 197, 2, 1 |
| 1, 1, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 197 x 1 x 1 x 2 x 1 = 151690
Therefore, the lowest common multiple of 197,985,154,385 is 151690.
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 985 x 154 x 385 = 11504928050
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
985 : 1, 5, 197, 985
154 : 1, 2, 7, 11, 14, 22, 77, 154
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,985,154,385, is 1.
Now, the common factors can be found like this.
197:197
985:5x 197
154:2x 7x 11
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 11x 197 = 75845
Therefore, the value for common factors is 75845.
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 = 11504928050/(1x75845)
LCM = 11504928050/75845
LCM = 151690
Thus, we can understand that the LCM of 197,985,154,385 is 151690.
