Given numbers are 161,689,419,265,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,689,419,265,667 is 6739491395.
Find LCM of 161,689,419,265,667 with Prime Factorization
| 23 | 161, 689, 419, 265, 667 |
| 53 | 7, 689, 419, 265, 29 |
| 7, 13, 419, 5, 29 |
Multiply the prime numbers at the bottom and the left side.
23 x 53 x 7 x 13 x 419 x 5 x 29 = 6739491395
Therefore, the lowest common multiple of 161,689,419,265,667 is 6739491395.
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.
161 x 689 x 419 x 265 x 667 = 8215440010505
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.
161 : 1, 7, 23, 161
689 : 1, 13, 53, 689
419 : 1, 419
265 : 1, 5, 53, 265
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,689,419,265,667, is 1.
Now, the common factors can be found like this.
161:7x 23
689:13x 53
419:419
265:5x 53
667:23x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 53 = 1219
Therefore, the value for common factors is 1219.
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 = 8215440010505/(1x1219)
LCM = 8215440010505/1219
LCM = 6739491395
Thus, we can understand that the LCM of 161,689,419,265,667 is 6739491395.
