Given numbers are 901,141,165,221,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,141,165,221,945 is 5722561845.
Find LCM of 901,141,165,221,945 with Prime Factorization
| 3 | 901, 141, 165, 221, 945 |
| 5 | 901, 47, 55, 221, 315 |
| 17 | 901, 47, 11, 221, 63 |
| 53, 47, 11, 13, 63 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 53 x 47 x 11 x 13 x 63 = 5722561845
Therefore, the lowest common multiple of 901,141,165,221,945 is 5722561845.
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.
901 x 141 x 165 x 221 x 945 = 4377759811425
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.
901 : 1, 17, 53, 901
141 : 1, 3, 47, 141
165 : 1, 3, 5, 11, 15, 33, 55, 165
221 : 1, 13, 17, 221
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,141,165,221,945, is 1.
Now, the common factors can be found like this.
901:17x 53
141:3x 47
165:3x 5x 11
221:13x 17
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 17 = 765
Therefore, the value for common factors is 765.
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 = 4377759811425/(1x765)
LCM = 4377759811425/765
LCM = 5722561845
Thus, we can understand that the LCM of 901,141,165,221,945 is 5722561845.
