Given numbers are 332,470,289,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 332,470,289,221 is 293121140.
Find LCM of 332,470,289,221 with Prime Factorization
| 2 | 332, 470, 289, 221 |
| 17 | 166, 235, 289, 221 |
| 166, 235, 17, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 166 x 235 x 17 x 13 = 293121140
Therefore, the lowest common multiple of 332,470,289,221 is 293121140.
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.
332 x 470 x 289 x 221 = 9966118760
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.
332 : 1, 2, 4, 83, 166, 332
470 : 1, 2, 5, 10, 47, 94, 235, 470
289 : 1, 17, 289
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 332,470,289,221, is 1.
Now, the common factors can be found like this.
332:2x 2x 83
470:2x 5x 47
289:17x 17
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 9966118760/(1x34)
LCM = 9966118760/34
LCM = 293121140
Thus, we can understand that the LCM of 332,470,289,221 is 293121140.
