Given numbers are 845,227,265,242,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,227,265,242,138 is 169755124110.
Find LCM of 845,227,265,242,138 with Prime Factorization
| 2 | 845, 227, 265, 242, 138 |
| 5 | 845, 227, 265, 121, 69 |
| 169, 227, 53, 121, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 169 x 227 x 53 x 121 x 69 = 169755124110
Therefore, the lowest common multiple of 845,227,265,242,138 is 169755124110.
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.
845 x 227 x 265 x 242 x 138 = 1697551241100
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.
845 : 1, 5, 13, 65, 169, 845
227 : 1, 227
265 : 1, 5, 53, 265
242 : 1, 2, 11, 22, 121, 242
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,227,265,242,138, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
227:227
265:5x 53
242:2x 11x 11
138:2x 3x 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 5 = 10
Therefore, the value for common factors is 10.
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 = 1697551241100/(1x10)
LCM = 1697551241100/10
LCM = 169755124110
Thus, we can understand that the LCM of 845,227,265,242,138 is 169755124110.
