Given numbers are 247,737,917,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,737,917,231 is 500789289.
Find LCM of 247,737,917,231 with Prime Factorization
| 7 | 247, 737, 917, 231 |
| 11 | 247, 737, 131, 33 |
| 247, 67, 131, 3 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 247 x 67 x 131 x 3 = 500789289
Therefore, the lowest common multiple of 247,737,917,231 is 500789289.
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.
247 x 737 x 917 x 231 = 38560775253
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.
247 : 1, 13, 19, 247
737 : 1, 11, 67, 737
917 : 1, 7, 131, 917
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,737,917,231, is 1.
Now, the common factors can be found like this.
247:13x 19
737:11x 67
917:7x 131
231:3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11 = 77
Therefore, the value for common factors is 77.
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 = 38560775253/(1x77)
LCM = 38560775253/77
LCM = 500789289
Thus, we can understand that the LCM of 247,737,917,231 is 500789289.
