Given numbers are 296,788,921,978,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 296,788,921,978,161 is 1409389552536.
Find LCM of 296,788,921,978,161 with Prime Factorization
| 2 | 296, 788, 921, 978, 161 |
| 2 | 148, 394, 921, 489, 161 |
| 3 | 74, 197, 921, 489, 161 |
| 74, 197, 307, 163, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 74 x 197 x 307 x 163 x 161 = 1409389552536
Therefore, the lowest common multiple of 296,788,921,978,161 is 1409389552536.
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.
296 x 788 x 921 x 978 x 161 = 33825349260864
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.
296 : 1, 2, 4, 8, 37, 74, 148, 296
788 : 1, 2, 4, 197, 394, 788
921 : 1, 3, 307, 921
978 : 1, 2, 3, 6, 163, 326, 489, 978
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 296,788,921,978,161, is 1.
Now, the common factors can be found like this.
296:2x 2x 2x 37
788:2x 2x 197
921:3x 307
978:2x 3x 163
161:7x 23
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 3 = 24
Therefore, the value for common factors is 24.
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 = 33825349260864/(1x24)
LCM = 33825349260864/24
LCM = 1409389552536
Thus, we can understand that the LCM of 296,788,921,978,161 is 1409389552536.
