Given numbers are 303,420,873,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 303,420,873,756 is 37032660.
Find LCM of 303,420,873,756 with Prime Factorization
| 2 | 303, 420, 873, 756 |
| 2 | 303, 210, 873, 378 |
| 3 | 303, 105, 873, 189 |
| 3 | 101, 35, 291, 63 |
| 7 | 101, 35, 97, 21 |
| 101, 5, 97, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 101 x 5 x 97 x 3 = 37032660
Therefore, the lowest common multiple of 303,420,873,756 is 37032660.
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.
303 x 420 x 873 x 756 = 83990072880
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.
303 : 1, 3, 101, 303
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
873 : 1, 3, 9, 97, 291, 873
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 303,420,873,756, is 3.
Now, the common factors can be found like this.
303:3x 101
420:2x 2x 3x 5x 7
873:3x 3x 97
756:2x 2x 3x 3x 3x 7
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 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 83990072880/(3x756)
LCM = 83990072880/2268
LCM = 37032660
Thus, we can understand that the LCM of 303,420,873,756 is 37032660.
