Given numbers are 677,847,697,459,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 677,847,697,459,391 is 248196959703.
Find LCM of 677,847,697,459,391 with Prime Factorization
17 | 677, 847, 697, 459, 391 |
677, 847, 41, 27, 23 |
Multiply the prime numbers at the bottom and the left side.
17 x 677 x 847 x 41 x 27 x 23 = 248196959703
Therefore, the lowest common multiple of 677,847,697,459,391 is 248196959703.
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.
677 x 847 x 697 x 459 x 391 = 71728921354167
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.
677 : 1, 677
847 : 1, 7, 11, 77, 121, 847
697 : 1, 17, 41, 697
459 : 1, 3, 9, 17, 27, 51, 153, 459
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,847,697,459,391, is 1.
Now, the common factors can be found like this.
677:677
847:7x 11x 11
697:17x 41
459:3x 3x 3x 17
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 17 = 289
Therefore, the value for common factors is 289.
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 = 71728921354167/(1x289)
LCM = 71728921354167/289
LCM = 248196959703
Thus, we can understand that the LCM of 677,847,697,459,391 is 248196959703.
