Find LCM of 992,896,721,209 with Prime Factorization
| 2 | 992, 896, 721, 209 |
| 2 | 496, 448, 721, 209 |
| 2 | 248, 224, 721, 209 |
| 2 | 124, 112, 721, 209 |
| 2 | 62, 56, 721, 209 |
| 7 | 31, 28, 721, 209 |
| 31, 4, 103, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 7 x 31 x 4 x 103 x 209 = 597933952
Therefore, the lowest common multiple of 992,896,721,209 is 597933952.
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.
992 x 896 x 721 x 209 = 133937205248
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.
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
721 : 1, 7, 103, 721
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 992,896,721,209, is 1.
Now, the common factors can be found like this.
992:2x 2x 2x 2x 2x 31
896:2x 2x 2x 2x 2x 2x 2x 7
721:7x 103
209:11x 19
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 7 = 224
Therefore, the value for common factors is 224.
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 = 133937205248/(1x224)
LCM = 133937205248/224
LCM = 597933952
Thus, we can understand that the LCM of 992,896,721,209 is 597933952.
