Given numbers are 271,643,765,692,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 271,643,765,692,168 is 1291444743960.
Find LCM of 271,643,765,692,168 with Prime Factorization
| 2 | 271, 643, 765, 692, 168 |
| 2 | 271, 643, 765, 346, 84 |
| 3 | 271, 643, 765, 173, 42 |
| 271, 643, 255, 173, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 271 x 643 x 255 x 173 x 14 = 1291444743960
Therefore, the lowest common multiple of 271,643,765,692,168 is 1291444743960.
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.
271 x 643 x 765 x 692 x 168 = 15497336927520
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.
271 : 1, 271
643 : 1, 643
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
692 : 1, 2, 4, 173, 346, 692
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 271,643,765,692,168, is 1.
Now, the common factors can be found like this.
271:271
643:643
765:3x 3x 5x 17
692:2x 2x 173
168:2x 2x 2x 3x 7
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 3 = 12
Therefore, the value for common factors is 12.
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 = 15497336927520/(1x12)
LCM = 15497336927520/12
LCM = 1291444743960
Thus, we can understand that the LCM of 271,643,765,692,168 is 1291444743960.
