Given numbers are 305,304,145,394,137
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,304,145,394,137 is 72570182320.
Find LCM of 305,304,145,394,137 with Prime Factorization
| 2 | 305, 304, 145, 394, 137 |
| 5 | 305, 152, 145, 197, 137 |
| 61, 152, 29, 197, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 61 x 152 x 29 x 197 x 137 = 72570182320
Therefore, the lowest common multiple of 305,304,145,394,137 is 72570182320.
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.
305 x 304 x 145 x 394 x 137 = 725701823200
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.
305 : 1, 5, 61, 305
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
145 : 1, 5, 29, 145
394 : 1, 2, 197, 394
137 : 1, 137
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,304,145,394,137, is 1.
Now, the common factors can be found like this.
305:5x 61
304:2x 2x 2x 2x 19
145:5x 29
394:2x 197
137:137
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 = 725701823200/(1x10)
LCM = 725701823200/10
LCM = 72570182320
Thus, we can understand that the LCM of 305,304,145,394,137 is 72570182320.
