The LCM of 197,168,396,460 is 125599320.
Find LCM of 197,168,396,460 with Prime Factorization
| 2 | 197, 168, 396, 460 |
| 2 | 197, 84, 198, 230 |
| 3 | 197, 42, 99, 115 |
| 197, 14, 33, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 197 x 14 x 33 x 115 = 125599320
Therefore, the lowest common multiple of 197,168,396,460 is 125599320.
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 168 x 396 x 460 = 6028767360
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
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,168,396,460, is 1.
Now, the common factors can be found like this.
197:197
168:2x 2x 2x 3x 7
396:2x 2x 3x 3x 11
460:2x 2x 5x 23
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 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 6028767360/(1x48)
LCM = 6028767360/48
LCM = 125599320
Thus, we can understand that the LCM of 197,168,396,460 is 125599320.
