Find LCM of 696,556,810,638,144 with Prime Factorization
| 2 | 696, 556, 810, 638, 144 |
| 2 | 348, 278, 405, 319, 72 |
| 2 | 174, 139, 405, 319, 36 |
| 3 | 87, 139, 405, 319, 18 |
| 3 | 29, 139, 135, 319, 6 |
| 29 | 29, 139, 45, 319, 2 |
| 1, 139, 45, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 29 x 1 x 139 x 45 x 11 x 2 = 287329680
Therefore, the lowest common multiple of 696,556,810,638,144 is 287329680.
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.
696 x 556 x 810 x 638 x 144 = 28797329848320
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.
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
556 : 1, 2, 4, 139, 278, 556
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
638 : 1, 2, 11, 22, 29, 58, 319, 638
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 696,556,810,638,144, is 2.
Now, the common factors can be found like this.
696:2x 2x 2x 3x 29
556:2x 2x 139
810:2x 3x 3x 3x 3x 5
638:2x 11x 29
144:2x 2x 2x 2x 3x 3
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 2x 2x 3x 3x 3x 29 = 50112
Therefore, the value for common factors is 50112.
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 = 28797329848320/(2x50112)
LCM = 28797329848320/100224
LCM = 287329680
Thus, we can understand that the LCM of 696,556,810,638,144 is 287329680.
