The LCM of 440,525,252,180 is 138600.
Find LCM of 440,525,252,180 with Prime Factorization
| 2 | 440, 525, 252, 180 |
| 2 | 220, 525, 126, 90 |
| 3 | 110, 525, 63, 45 |
| 3 | 110, 175, 21, 15 |
| 5 | 110, 175, 7, 5 |
| 7 | 22, 35, 7, 1 |
| 22, 5, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 22 x 5 x 1 x 1 = 138600
Therefore, the lowest common multiple of 440,525,252,180 is 138600.
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 525 x 252 x 180 = 10478160000
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
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
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 440,525,252,180, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
525:3x 5x 5x 7
252:2x 2x 3x 3x 7
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 3x 5x 5x 7 = 75600
Therefore, the value for common factors is 75600.
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 = 10478160000/(1x75600)
LCM = 10478160000/75600
LCM = 138600
Thus, we can understand that the LCM of 440,525,252,180 is 138600.
