Given numbers are 422,845,180,360
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,845,180,360 is 12837240.
Find LCM of 422,845,180,360 with Prime Factorization
| 2 | 422, 845, 180, 360 |
| 2 | 211, 845, 90, 180 |
| 3 | 211, 845, 45, 90 |
| 3 | 211, 845, 15, 30 |
| 5 | 211, 845, 5, 10 |
| 211, 169, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 211 x 169 x 1 x 2 = 12837240
Therefore, the lowest common multiple of 422,845,180,360 is 12837240.
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.
422 x 845 x 180 x 360 = 23107032000
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.
422 : 1, 2, 211, 422
845 : 1, 5, 13, 65, 169, 845
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,845,180,360, is 1.
Now, the common factors can be found like this.
422:2x 211
845:5x 13x 13
180:2x 2x 3x 3x 5
360:2x 2x 2x 3x 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 2x 2x 3x 3x 5x 5 = 1800
Therefore, the value for common factors is 1800.
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 = 23107032000/(1x1800)
LCM = 23107032000/1800
LCM = 12837240
Thus, we can understand that the LCM of 422,845,180,360 is 12837240.
