Find LCM of 199,665,728,224,245 with Prime Factorization
| 2 | 199, 665, 728, 224, 245 |
| 2 | 199, 665, 364, 112, 245 |
| 2 | 199, 665, 182, 56, 245 |
| 5 | 199, 665, 91, 28, 245 |
| 7 | 199, 133, 91, 28, 49 |
| 199, 19, 13, 4, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 199 x 19 x 13 x 4 x 7 = 385359520
Therefore, the lowest common multiple of 199,665,728,224,245 is 385359520.
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.
199 x 665 x 728 x 224 x 245 = 5287132614400
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.
199 : 1, 199
665 : 1, 5, 7, 19, 35, 95, 133, 665
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,665,728,224,245, is 1.
Now, the common factors can be found like this.
199:199
665:5x 7x 19
728:2x 2x 2x 7x 13
224:2x 2x 2x 2x 2x 7
245:5x 7x 7
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 5x 7x 7x 7 = 13720
Therefore, the value for common factors is 13720.
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 = 5287132614400/(1x13720)
LCM = 5287132614400/13720
LCM = 385359520
Thus, we can understand that the LCM of 199,665,728,224,245 is 385359520.
