Given numbers are 379,791,686,758
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 379,791,686,758 is 29379322.
Find LCM of 379,791,686,758 with Prime Factorization
| 2 | 379, 791, 686, 758 |
| 7 | 379, 791, 343, 379 |
| 379 | 379, 113, 49, 379 |
| 1, 113, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 379 x 1 x 113 x 49 x 1 = 29379322
Therefore, the lowest common multiple of 379,791,686,758 is 29379322.
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.
379 x 791 x 686 x 758 = 155886682532
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.
379 : 1, 379
791 : 1, 7, 113, 791
686 : 1, 2, 7, 14, 49, 98, 343, 686
758 : 1, 2, 379, 758
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 379,791,686,758, is 1.
Now, the common factors can be found like this.
379:379
791:7x 113
686:2x 7x 7x 7
758:2x 379
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 379 = 5306
Therefore, the value for common factors is 5306.
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 = 155886682532/(1x5306)
LCM = 155886682532/5306
LCM = 29379322
Thus, we can understand that the LCM of 379,791,686,758 is 29379322.
