Given numbers are 440,890,640,227
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,890,640,227 is 142229120.
Find LCM of 440,890,640,227 with Prime Factorization
| 2 | 440, 890, 640, 227 |
| 2 | 220, 445, 320, 227 |
| 2 | 110, 445, 160, 227 |
| 5 | 55, 445, 80, 227 |
| 11, 89, 16, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 89 x 16 x 227 = 142229120
Therefore, the lowest common multiple of 440,890,640,227 is 142229120.
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.
440 x 890 x 640 x 227 = 56891648000
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
890 : 1, 2, 5, 10, 89, 178, 445, 890
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
227 : 1, 227
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,890,640,227, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
890:2x 5x 89
640:2x 2x 2x 2x 2x 2x 2x 5
227:227
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 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 56891648000/(1x400)
LCM = 56891648000/400
LCM = 142229120
Thus, we can understand that the LCM of 440,890,640,227 is 142229120.
