Find LCM of 987,117,434,774,547 with Prime Factorization
| 2 | 987, 117, 434, 774, 547 |
| 3 | 987, 117, 217, 387, 547 |
| 3 | 329, 39, 217, 129, 547 |
| 7 | 329, 13, 217, 43, 547 |
| 47, 13, 31, 43, 547 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 47 x 13 x 31 x 43 x 547 = 56134418886
Therefore, the lowest common multiple of 987,117,434,774,547 is 56134418886.
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.
987 x 117 x 434 x 774 x 547 = 21218810338908
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
117 : 1, 3, 9, 13, 39, 117
434 : 1, 2, 7, 14, 31, 62, 217, 434
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
547 : 1, 547
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,117,434,774,547, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
117:3x 3x 13
434:2x 7x 31
774:2x 3x 3x 43
547:547
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 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 21218810338908/(1x378)
LCM = 21218810338908/378
LCM = 56134418886
Thus, we can understand that the LCM of 987,117,434,774,547 is 56134418886.
