The LCM of 291,288,556,976 is 236869344.
Find LCM of 291,288,556,976 with Prime Factorization
| 2 | 291, 288, 556, 976 |
| 2 | 291, 144, 278, 488 |
| 2 | 291, 72, 139, 244 |
| 2 | 291, 36, 139, 122 |
| 3 | 291, 18, 139, 61 |
| 97, 6, 139, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 97 x 6 x 139 x 61 = 236869344
Therefore, the lowest common multiple of 291,288,556,976 is 236869344.
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.
291 x 288 x 556 x 976 = 45478914048
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.
291 : 1, 3, 97, 291
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
556 : 1, 2, 4, 139, 278, 556
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,288,556,976, is 1.
Now, the common factors can be found like this.
291:3x 97
288:2x 2x 2x 2x 2x 3x 3
556:2x 2x 139
976:2x 2x 2x 2x 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 2x 2x 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 45478914048/(1x192)
LCM = 45478914048/192
LCM = 236869344
Thus, we can understand that the LCM of 291,288,556,976 is 236869344.
