Given numbers are 617,630,261,485
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 617,630,261,485 is 1093441230.
Find LCM of 617,630,261,485 with Prime Factorization
| 3 | 617, 630, 261, 485 |
| 3 | 617, 210, 87, 485 |
| 5 | 617, 70, 29, 485 |
| 617, 14, 29, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 617 x 14 x 29 x 97 = 1093441230
Therefore, the lowest common multiple of 617,630,261,485 is 1093441230.
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.
617 x 630 x 261 x 485 = 49204855350
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.
617 : 1, 617
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
261 : 1, 3, 9, 29, 87, 261
485 : 1, 5, 97, 485
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,630,261,485, is 1.
Now, the common factors can be found like this.
617:617
630:2x 3x 3x 5x 7
261:3x 3x 29
485:5x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 49204855350/(1x45)
LCM = 49204855350/45
LCM = 1093441230
Thus, we can understand that the LCM of 617,630,261,485 is 1093441230.
