Given numbers are 691,884,338,977
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,884,338,977 is 7758329644.
Find LCM of 691,884,338,977 with Prime Factorization
| 2 | 691, 884, 338, 977 |
| 13 | 691, 442, 169, 977 |
| 691, 34, 13, 977 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 691 x 34 x 13 x 977 = 7758329644
Therefore, the lowest common multiple of 691,884,338,977 is 7758329644.
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.
691 x 884 x 338 x 977 = 201716570744
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.
691 : 1, 691
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
338 : 1, 2, 13, 26, 169, 338
977 : 1, 977
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,884,338,977, is 1.
Now, the common factors can be found like this.
691:691
884:2x 2x 13x 17
338:2x 13x 13
977:977
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 201716570744/(1x26)
LCM = 201716570744/26
LCM = 7758329644
Thus, we can understand that the LCM of 691,884,338,977 is 7758329644.
