Given numbers are 788,796,660,245,955
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,796,660,245,955 is 242154578820.
Find LCM of 788,796,660,245,955 with Prime Factorization
| 2 | 788, 796, 660, 245, 955 |
| 2 | 394, 398, 330, 245, 955 |
| 5 | 197, 199, 165, 245, 955 |
| 197, 199, 33, 49, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 197 x 199 x 33 x 49 x 191 = 242154578820
Therefore, the lowest common multiple of 788,796,660,245,955 is 242154578820.
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.
788 x 796 x 660 x 245 x 955 = 96861831528000
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.
788 : 1, 2, 4, 197, 394, 788
796 : 1, 2, 4, 199, 398, 796
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
245 : 1, 5, 7, 35, 49, 245
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,796,660,245,955, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
796:2x 2x 199
660:2x 2x 3x 5x 11
245:5x 7x 7
955:5x 191
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 2x 2x 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 96861831528000/(1x400)
LCM = 96861831528000/400
LCM = 242154578820
Thus, we can understand that the LCM of 788,796,660,245,955 is 242154578820.
