Given numbers are 665,360,244,180
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,360,244,180 is 2920680.
Find LCM of 665,360,244,180 with Prime Factorization
| 2 | 665, 360, 244, 180 |
| 2 | 665, 180, 122, 90 |
| 3 | 665, 45, 61, 90 |
| 3 | 665, 15, 61, 30 |
| 5 | 665, 5, 61, 10 |
| 133, 1, 61, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 133 x 1 x 61 x 2 = 2920680
Therefore, the lowest common multiple of 665,360,244,180 is 2920680.
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.
665 x 360 x 244 x 180 = 10514448000
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
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
244 : 1, 2, 4, 61, 122, 244
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,360,244,180, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
360:2x 2x 2x 3x 3x 5
244:2x 2x 61
180:2x 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 2x 3x 3x 5x 5 = 3600
Therefore, the value for common factors is 3600.
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 = 10514448000/(1x3600)
LCM = 10514448000/3600
LCM = 2920680
Thus, we can understand that the LCM of 665,360,244,180 is 2920680.
