Given numbers are 669,431,731,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,431,731,187 is 2318533899.
Find LCM of 669,431,731,187 with Prime Factorization
| 17 | 669, 431, 731, 187 |
| 669, 431, 43, 11 |
Multiply the prime numbers at the bottom and the left side.
17 x 669 x 431 x 43 x 11 = 2318533899
Therefore, the lowest common multiple of 669,431,731,187 is 2318533899.
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.
669 x 431 x 731 x 187 = 39415076283
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.
669 : 1, 3, 223, 669
431 : 1, 431
731 : 1, 17, 43, 731
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,431,731,187, is 1.
Now, the common factors can be found like this.
669:3x 223
431:431
731:17x 43
187:11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 39415076283/(1x17)
LCM = 39415076283/17
LCM = 2318533899
Thus, we can understand that the LCM of 669,431,731,187 is 2318533899.
