Given numbers are 295,771,645,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 295,771,645,649 is 107581485.
Find LCM of 295,771,645,649 with Prime Factorization
| 3 | 295, 771, 645, 649 |
| 5 | 295, 257, 215, 649 |
| 59 | 59, 257, 43, 649 |
| 1, 257, 43, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 59 x 1 x 257 x 43 x 11 = 107581485
Therefore, the lowest common multiple of 295,771,645,649 is 107581485.
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.
295 x 771 x 645 x 649 = 95209614225
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.
295 : 1, 5, 59, 295
771 : 1, 3, 257, 771
645 : 1, 3, 5, 15, 43, 129, 215, 645
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 295,771,645,649, is 1.
Now, the common factors can be found like this.
295:5x 59
771:3x 257
645:3x 5x 43
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 59 = 885
Therefore, the value for common factors is 885.
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 = 95209614225/(1x885)
LCM = 95209614225/885
LCM = 107581485
Thus, we can understand that the LCM of 295,771,645,649 is 107581485.
