Given numbers are 231,505,338,749,951
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,505,338,749,951 is 1337405479410.
Find LCM of 231,505,338,749,951 with Prime Factorization
| 3 | 231, 505, 338, 749, 951 |
| 7 | 77, 505, 338, 749, 317 |
| 11, 505, 338, 107, 317 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 505 x 338 x 107 x 317 = 1337405479410
Therefore, the lowest common multiple of 231,505,338,749,951 is 1337405479410.
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.
231 x 505 x 338 x 749 x 951 = 28085515067610
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
505 : 1, 5, 101, 505
338 : 1, 2, 13, 26, 169, 338
749 : 1, 7, 107, 749
951 : 1, 3, 317, 951
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,505,338,749,951, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
505:5x 101
338:2x 13x 13
749:7x 107
951:3x 317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 28085515067610/(1x21)
LCM = 28085515067610/21
LCM = 1337405479410
Thus, we can understand that the LCM of 231,505,338,749,951 is 1337405479410.
