Find LCM of 987,544,976,340 with Prime Factorization
| 2 | 987, 544, 976, 340 |
| 2 | 987, 272, 488, 170 |
| 2 | 987, 136, 244, 85 |
| 2 | 987, 68, 122, 85 |
| 17 | 987, 34, 61, 85 |
| 987, 2, 61, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 17 x 987 x 2 x 61 x 5 = 163763040
Therefore, the lowest common multiple of 987,544,976,340 is 163763040.
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 544 x 976 x 340 = 178174187520
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
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,544,976,340, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
544:2x 2x 2x 2x 2x 17
976:2x 2x 2x 2x 61
340:2x 2x 5x 17
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 17 = 1088
Therefore, the value for common factors is 1088.
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 = 178174187520/(1x1088)
LCM = 178174187520/1088
LCM = 163763040
Thus, we can understand that the LCM of 987,544,976,340 is 163763040.
