Given numbers are 789,681,364,706
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,681,364,706 is 23013302676.
Find LCM of 789,681,364,706 with Prime Factorization
| 2 | 789, 681, 364, 706 |
| 3 | 789, 681, 182, 353 |
| 263, 227, 182, 353 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 263 x 227 x 182 x 353 = 23013302676
Therefore, the lowest common multiple of 789,681,364,706 is 23013302676.
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.
789 x 681 x 364 x 706 = 138079816056
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.
789 : 1, 3, 263, 789
681 : 1, 3, 227, 681
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
706 : 1, 2, 353, 706
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,681,364,706, is 1.
Now, the common factors can be found like this.
789:3x 263
681:3x 227
364:2x 2x 7x 13
706:2x 353
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 138079816056/(1x6)
LCM = 138079816056/6
LCM = 23013302676
Thus, we can understand that the LCM of 789,681,364,706 is 23013302676.
