Given numbers are 290,831,303,960
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,831,303,960 is 778879680.
Find LCM of 290,831,303,960 with Prime Factorization
| 2 | 290, 831, 303, 960 |
| 3 | 145, 831, 303, 480 |
| 5 | 145, 277, 101, 160 |
| 29, 277, 101, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 29 x 277 x 101 x 32 = 778879680
Therefore, the lowest common multiple of 290,831,303,960 is 778879680.
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.
290 x 831 x 303 x 960 = 70099171200
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
831 : 1, 3, 277, 831
303 : 1, 3, 101, 303
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,831,303,960, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
831:3x 277
303:3x 101
960:2x 2x 2x 2x 2x 2x 3x 5
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 70099171200/(1x90)
LCM = 70099171200/90
LCM = 778879680
Thus, we can understand that the LCM of 290,831,303,960 is 778879680.
