Given numbers are 258,249,921,122,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 258,249,921,122,551 is 220962007878.
Find LCM of 258,249,921,122,551 with Prime Factorization
| 2 | 258, 249, 921, 122, 551 |
| 3 | 129, 249, 921, 61, 551 |
| 43, 83, 307, 61, 551 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 83 x 307 x 61 x 551 = 220962007878
Therefore, the lowest common multiple of 258,249,921,122,551 is 220962007878.
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.
258 x 249 x 921 x 122 x 551 = 3977316141804
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.
258 : 1, 2, 3, 6, 43, 86, 129, 258
249 : 1, 3, 83, 249
921 : 1, 3, 307, 921
122 : 1, 2, 61, 122
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,249,921,122,551, is 1.
Now, the common factors can be found like this.
258:2x 3x 43
249:3x 83
921:3x 307
122:2x 61
551:19x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 3977316141804/(1x18)
LCM = 3977316141804/18
LCM = 220962007878
Thus, we can understand that the LCM of 258,249,921,122,551 is 220962007878.
