Given numbers are 965,473,687,215,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 965,473,687,215,420 is 8780176020.
Find LCM of 965,473,687,215,420 with Prime Factorization
| 3 | 965, 473, 687, 215, 420 |
| 5 | 965, 473, 229, 215, 140 |
| 43 | 193, 473, 229, 43, 28 |
| 193, 11, 229, 1, 28 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 193 x 11 x 229 x 1 x 28 = 8780176020
Therefore, the lowest common multiple of 965,473,687,215,420 is 8780176020.
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.
965 x 473 x 687 x 215 x 420 = 28316067664500
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.
965 : 1, 5, 193, 965
473 : 1, 11, 43, 473
687 : 1, 3, 229, 687
215 : 1, 5, 43, 215
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 965,473,687,215,420, is 1.
Now, the common factors can be found like this.
965:5x 193
473:11x 43
687:3x 229
215:5x 43
420:2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 43 = 3225
Therefore, the value for common factors is 3225.
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 = 28316067664500/(1x3225)
LCM = 28316067664500/3225
LCM = 8780176020
Thus, we can understand that the LCM of 965,473,687,215,420 is 8780176020.
