Given numbers are 810,660,960,669,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,660,960,669,545 is 6930411840.
Find LCM of 810,660,960,669,545 with Prime Factorization
| 2 | 810, 660, 960, 669, 545 |
| 2 | 405, 330, 480, 669, 545 |
| 3 | 405, 165, 240, 669, 545 |
| 5 | 135, 55, 80, 223, 545 |
| 27, 11, 16, 223, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 27 x 11 x 16 x 223 x 109 = 6930411840
Therefore, the lowest common multiple of 810,660,960,669,545 is 6930411840.
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.
810 x 660 x 960 x 669 x 545 = 187121119680000
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
669 : 1, 3, 223, 669
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,660,960,669,545, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
660:2x 2x 3x 5x 11
960:2x 2x 2x 2x 2x 2x 3x 5
669:3x 223
545:5x 109
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 3x 5x 5x 5 = 27000
Therefore, the value for common factors is 27000.
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 = 187121119680000/(1x27000)
LCM = 187121119680000/27000
LCM = 6930411840
Thus, we can understand that the LCM of 810,660,960,669,545 is 6930411840.
