Given numbers are 661,731,339,369
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,731,339,369 is 20147615127.
Find LCM of 661,731,339,369 with Prime Factorization
| 3 | 661, 731, 339, 369 |
| 661, 731, 113, 123 |
Multiply the prime numbers at the bottom and the left side.
3 x 661 x 731 x 113 x 123 = 20147615127
Therefore, the lowest common multiple of 661,731,339,369 is 20147615127.
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.
661 x 731 x 339 x 369 = 60442845381
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.
661 : 1, 661
731 : 1, 17, 43, 731
339 : 1, 3, 113, 339
369 : 1, 3, 9, 41, 123, 369
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,731,339,369, is 1.
Now, the common factors can be found like this.
661:661
731:17x 43
339:3x 113
369:3x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 60442845381/(1x3)
LCM = 60442845381/3
LCM = 20147615127
Thus, we can understand that the LCM of 661,731,339,369 is 20147615127.
