Find LCM of 547,705,693,315 with Prime Factorization
| 3 | 547, 705, 693, 315 |
| 3 | 547, 235, 231, 105 |
| 5 | 547, 235, 77, 35 |
| 7 | 547, 47, 77, 7 |
| 547, 47, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 547 x 47 x 11 x 1 = 89081685
Therefore, the lowest common multiple of 547,705,693,315 is 89081685.
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.
547 x 705 x 693 x 315 = 84182192325
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.
547 : 1, 547
705 : 1, 3, 5, 15, 47, 141, 235, 705
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 547,705,693,315, is 1.
Now, the common factors can be found like this.
547:547
705:3x 5x 47
693:3x 3x 7x 11
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 7 = 945
Therefore, the value for common factors is 945.
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 = 84182192325/(1x945)
LCM = 84182192325/945
LCM = 89081685
Thus, we can understand that the LCM of 547,705,693,315 is 89081685.
