Find LCM of 198,126,224,445 with Prime Factorization
| 2 | 198, 126, 224, 445 |
| 3 | 99, 63, 112, 445 |
| 3 | 33, 21, 112, 445 |
| 7 | 11, 7, 112, 445 |
| 11, 1, 16, 445 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 11 x 1 x 16 x 445 = 9868320
Therefore, the lowest common multiple of 198,126,224,445 is 9868320.
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.
198 x 126 x 224 x 445 = 2486816640
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
445 : 1, 5, 89, 445
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,126,224,445, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
126:2x 3x 3x 7
224:2x 2x 2x 2x 2x 7
445:5x 89
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 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 2486816640/(1x252)
LCM = 2486816640/252
LCM = 9868320
Thus, we can understand that the LCM of 198,126,224,445 is 9868320.
