Given numbers are 253,831,121,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,831,121,989 is 99444939.
Find LCM of 253,831,121,989 with Prime Factorization
| 11 | 253, 831, 121, 989 |
| 23 | 23, 831, 11, 989 |
| 1, 831, 11, 43 |
Multiply the prime numbers at the bottom and the left side.
11 x 23 x 1 x 831 x 11 x 43 = 99444939
Therefore, the lowest common multiple of 253,831,121,989 is 99444939.
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.
253 x 831 x 121 x 989 = 25159569567
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.
253 : 1, 11, 23, 253
831 : 1, 3, 277, 831
121 : 1, 11, 121
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,831,121,989, is 1.
Now, the common factors can be found like this.
253:11x 23
831:3x 277
121:11x 11
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 23 = 253
Therefore, the value for common factors is 253.
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 = 25159569567/(1x253)
LCM = 25159569567/253
LCM = 99444939
Thus, we can understand that the LCM of 253,831,121,989 is 99444939.
