Given numbers are 304,455,231,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 304,455,231,620 is 141501360.
Find LCM of 304,455,231,620 with Prime Factorization
| 2 | 304, 455, 231, 620 |
| 2 | 152, 455, 231, 310 |
| 5 | 76, 455, 231, 155 |
| 7 | 76, 91, 231, 31 |
| 76, 13, 33, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 76 x 13 x 33 x 31 = 141501360
Therefore, the lowest common multiple of 304,455,231,620 is 141501360.
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.
304 x 455 x 231 x 620 = 19810190400
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.
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
455 : 1, 5, 7, 13, 35, 65, 91, 455
231 : 1, 3, 7, 11, 21, 33, 77, 231
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 304,455,231,620, is 1.
Now, the common factors can be found like this.
304:2x 2x 2x 2x 19
455:5x 7x 13
231:3x 7x 11
620:2x 2x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 19810190400/(1x140)
LCM = 19810190400/140
LCM = 141501360
Thus, we can understand that the LCM of 304,455,231,620 is 141501360.
