Find LCM of 815,170,163,658,987 with Prime Factorization
| 2 | 815, 170, 163, 658, 987 |
| 5 | 815, 85, 163, 329, 987 |
| 7 | 163, 17, 163, 329, 987 |
| 47 | 163, 17, 163, 47, 141 |
| 163 | 163, 17, 163, 1, 3 |
| 1, 17, 1, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 47 x 163 x 1 x 17 x 1 x 1 x 3 = 27349770
Therefore, the lowest common multiple of 815,170,163,658,987 is 27349770.
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.
815 x 170 x 163 x 658 x 987 = 14666861157900
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.
815 : 1, 5, 163, 815
170 : 1, 2, 5, 10, 17, 34, 85, 170
163 : 1, 163
658 : 1, 2, 7, 14, 47, 94, 329, 658
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,170,163,658,987, is 1.
Now, the common factors can be found like this.
815:5x 163
170:2x 5x 17
163:163
658:2x 7x 47
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 47x 163 = 536270
Therefore, the value for common factors is 536270.
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 = 14666861157900/(1x536270)
LCM = 14666861157900/536270
LCM = 27349770
Thus, we can understand that the LCM of 815,170,163,658,987 is 27349770.
