The LCM of 165,720,215,694 is 118174320.
Find LCM of 165,720,215,694 with Prime Factorization
| 2 | 165, 720, 215, 694 |
| 3 | 165, 360, 215, 347 |
| 5 | 55, 120, 215, 347 |
| 11, 24, 43, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 24 x 43 x 347 = 118174320
Therefore, the lowest common multiple of 165,720,215,694 is 118174320.
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.
165 x 720 x 215 x 694 = 17726148000
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
215 : 1, 5, 43, 215
694 : 1, 2, 347, 694
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,720,215,694, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
720:2x 2x 2x 2x 3x 3x 5
215:5x 43
694:2x 347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 17726148000/(1x150)
LCM = 17726148000/150
LCM = 118174320
Thus, we can understand that the LCM of 165,720,215,694 is 118174320.
