Given numbers are 236,215,360,420,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 236,215,360,420,815 is 1042098120.
Find LCM of 236,215,360,420,815 with Prime Factorization
| 2 | 236, 215, 360, 420, 815 |
| 2 | 118, 215, 180, 210, 815 |
| 3 | 59, 215, 90, 105, 815 |
| 5 | 59, 215, 30, 35, 815 |
| 59, 43, 6, 7, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 59 x 43 x 6 x 7 x 163 = 1042098120
Therefore, the lowest common multiple of 236,215,360,420,815 is 1042098120.
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.
236 x 215 x 360 x 420 x 815 = 6252588720000
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.
236 : 1, 2, 4, 59, 118, 236
215 : 1, 5, 43, 215
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
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
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 236,215,360,420,815, is 1.
Now, the common factors can be found like this.
236:2x 2x 59
215:5x 43
360:2x 2x 2x 3x 3x 5
420:2x 2x 3x 5x 7
815:5x 163
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 3x 5x 5x 5 = 6000
Therefore, the value for common factors is 6000.
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 = 6252588720000/(1x6000)
LCM = 6252588720000/6000
LCM = 1042098120
Thus, we can understand that the LCM of 236,215,360,420,815 is 1042098120.
