Given numbers are 647,455,197,285,610
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,455,197,285,610 is 403289198130.
Find LCM of 647,455,197,285,610 with Prime Factorization
| 5 | 647, 455, 197, 285, 610 |
| 647, 91, 197, 57, 122 |
Multiply the prime numbers at the bottom and the left side.
5 x 647 x 91 x 197 x 57 x 122 = 403289198130
Therefore, the lowest common multiple of 647,455,197,285,610 is 403289198130.
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.
647 x 455 x 197 x 285 x 610 = 10082229953250
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.
647 : 1, 647
455 : 1, 5, 7, 13, 35, 65, 91, 455
197 : 1, 197
285 : 1, 3, 5, 15, 19, 57, 95, 285
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 647,455,197,285,610, is 1.
Now, the common factors can be found like this.
647:647
455:5x 7x 13
197:197
285:3x 5x 19
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.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 10082229953250/(1x25)
LCM = 10082229953250/25
LCM = 403289198130
Thus, we can understand that the LCM of 647,455,197,285,610 is 403289198130.
