Given numbers are 305,298,116,610,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,298,116,610,391 is 2061203420.
Find LCM of 305,298,116,610,391 with Prime Factorization
| 2 | 305, 298, 116, 610, 391 |
| 5 | 305, 149, 58, 305, 391 |
| 61 | 61, 149, 58, 61, 391 |
| 1, 149, 58, 1, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 61 x 1 x 149 x 58 x 1 x 391 = 2061203420
Therefore, the lowest common multiple of 305,298,116,610,391 is 2061203420.
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 298 x 116 x 610 x 391 = 2514668172400
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
298 : 1, 2, 149, 298
116 : 1, 2, 4, 29, 58, 116
610 : 1, 2, 5, 10, 61, 122, 305, 610
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,298,116,610,391, is 1.
Now, the common factors can be found like this.
305:5x 61
298:2x 149
116:2x 2x 29
610:2x 5x 61
391:17x 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 2x 5x 61 = 1220
Therefore, the value for common factors is 1220.
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 = 2514668172400/(1x1220)
LCM = 2514668172400/1220
LCM = 2061203420
Thus, we can understand that the LCM of 305,298,116,610,391 is 2061203420.
