Given numbers are 187,546,611,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,546,611,731 is 206348142.
Find LCM of 187,546,611,731 with Prime Factorization
| 13 | 187, 546, 611, 731 |
| 17 | 187, 42, 47, 731 |
| 11, 42, 47, 43 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 11 x 42 x 47 x 43 = 206348142
Therefore, the lowest common multiple of 187,546,611,731 is 206348142.
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.
187 x 546 x 611 x 731 = 45602939382
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.
187 : 1, 11, 17, 187
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
611 : 1, 13, 47, 611
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,546,611,731, is 1.
Now, the common factors can be found like this.
187:11x 17
546:2x 3x 7x 13
611:13x 47
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 45602939382/(1x221)
LCM = 45602939382/221
LCM = 206348142
Thus, we can understand that the LCM of 187,546,611,731 is 206348142.
