Find LCM of 256,192,691,698,909 with Prime Factorization
| 2 | 256, 192, 691, 698, 909 |
| 2 | 128, 96, 691, 349, 909 |
| 2 | 64, 48, 691, 349, 909 |
| 2 | 32, 24, 691, 349, 909 |
| 2 | 16, 12, 691, 349, 909 |
| 2 | 8, 6, 691, 349, 909 |
| 3 | 4, 3, 691, 349, 909 |
| 4, 1, 691, 349, 303 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 4 x 1 x 691 x 349 x 303 = 56118663936
Therefore, the lowest common multiple of 256,192,691,698,909 is 56118663936.
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.
256 x 192 x 691 x 698 x 909 = 21549566951424
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
691 : 1, 691
698 : 1, 2, 349, 698
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,192,691,698,909, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
192:2x 2x 2x 2x 2x 2x 3
691:691
698:2x 349
909:3x 3x 101
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 2x 3 = 384
Therefore, the value for common factors is 384.
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 = 21549566951424/(1x384)
LCM = 21549566951424/384
LCM = 56118663936
Thus, we can understand that the LCM of 256,192,691,698,909 is 56118663936.
