Find LCM of 199,898,428,688,672 with Prime Factorization
| 2 | 199, 898, 428, 688, 672 |
| 2 | 199, 449, 214, 344, 336 |
| 2 | 199, 449, 107, 172, 168 |
| 2 | 199, 449, 107, 86, 84 |
| 199, 449, 107, 43, 42 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 199 x 449 x 107 x 43 x 42 = 276261855072
Therefore, the lowest common multiple of 199,898,428,688,672 is 276261855072.
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 898 x 428 x 688 x 672 = 35361517449216
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
898 : 1, 2, 449, 898
428 : 1, 2, 4, 107, 214, 428
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,898,428,688,672, is 1.
Now, the common factors can be found like this.
199:199
898:2x 449
428:2x 2x 107
688:2x 2x 2x 2x 43
672:2x 2x 2x 2x 2x 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.
2x 2x 2x 2x 2x 2x 2 = 128
Therefore, the value for common factors is 128.
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 = 35361517449216/(1x128)
LCM = 35361517449216/128
LCM = 276261855072
Thus, we can understand that the LCM of 199,898,428,688,672 is 276261855072.
