Given numbers are 675,122,309,610
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 675,122,309,610 is 8482050.
Find LCM of 675,122,309,610 with Prime Factorization
| 2 | 675, 122, 309, 610 |
| 3 | 675, 61, 309, 305 |
| 5 | 225, 61, 103, 305 |
| 61 | 45, 61, 103, 61 |
| 45, 1, 103, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 61 x 45 x 1 x 103 x 1 = 8482050
Therefore, the lowest common multiple of 675,122,309,610 is 8482050.
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.
675 x 122 x 309 x 610 = 15522151500
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.
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
122 : 1, 2, 61, 122
309 : 1, 3, 103, 309
610 : 1, 2, 5, 10, 61, 122, 305, 610
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 675,122,309,610, is 1.
Now, the common factors can be found like this.
675:3x 3x 3x 5x 5
122:2x 61
309:3x 103
610:2x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 61 = 1830
Therefore, the value for common factors is 1830.
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 = 15522151500/(1x1830)
LCM = 15522151500/1830
LCM = 8482050
Thus, we can understand that the LCM of 675,122,309,610 is 8482050.
