Find LCM of 168,468,781,693,727 with Prime Factorization
| 2 | 168, 468, 781, 693, 727 |
| 2 | 84, 234, 781, 693, 727 |
| 3 | 42, 117, 781, 693, 727 |
| 3 | 14, 39, 781, 231, 727 |
| 7 | 14, 13, 781, 77, 727 |
| 11 | 2, 13, 781, 11, 727 |
| 2, 13, 71, 1, 727 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 11 x 2 x 13 x 71 x 1 x 727 = 3720140424
Therefore, the lowest common multiple of 168,468,781,693,727 is 3720140424.
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.
168 x 468 x 781 x 693 x 727 = 30936687765984
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
781 : 1, 11, 71, 781
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
727 : 1, 727
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,468,781,693,727, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
468:2x 2x 3x 3x 13
781:11x 71
693:3x 3x 7x 11
727:727
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 3x 3x 3x 7x 11 = 8316
Therefore, the value for common factors is 8316.
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 = 30936687765984/(1x8316)
LCM = 30936687765984/8316
LCM = 3720140424
Thus, we can understand that the LCM of 168,468,781,693,727 is 3720140424.
