Given numbers are 623,749,989,161,271
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,749,989,161,271 is 17866414559.
Find LCM of 623,749,989,161,271 with Prime Factorization
| 7 | 623, 749, 989, 161, 271 |
| 23 | 89, 107, 989, 23, 271 |
| 89, 107, 43, 1, 271 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 89 x 107 x 43 x 1 x 271 = 17866414559
Therefore, the lowest common multiple of 623,749,989,161,271 is 17866414559.
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.
623 x 749 x 989 x 161 x 271 = 20135449207993
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.
623 : 1, 7, 89, 623
749 : 1, 7, 107, 749
989 : 1, 23, 43, 989
161 : 1, 7, 23, 161
271 : 1, 271
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,749,989,161,271, is 1.
Now, the common factors can be found like this.
623:7x 89
749:7x 107
989:23x 43
161:7x 23
271:271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 23 = 1127
Therefore, the value for common factors is 1127.
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 = 20135449207993/(1x1127)
LCM = 20135449207993/1127
LCM = 17866414559
Thus, we can understand that the LCM of 623,749,989,161,271 is 17866414559.
