Given numbers are 689,966,759,622
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,966,759,622 is 2276928654.
Find LCM of 689,966,759,622 with Prime Factorization
| 2 | 689, 966, 759, 622 |
| 3 | 689, 483, 759, 311 |
| 23 | 689, 161, 253, 311 |
| 689, 7, 11, 311 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 689 x 7 x 11 x 311 = 2276928654
Therefore, the lowest common multiple of 689,966,759,622 is 2276928654.
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.
689 x 966 x 759 x 622 = 314216154252
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.
689 : 1, 13, 53, 689
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
759 : 1, 3, 11, 23, 33, 69, 253, 759
622 : 1, 2, 311, 622
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,966,759,622, is 1.
Now, the common factors can be found like this.
689:13x 53
966:2x 3x 7x 23
759:3x 11x 23
622:2x 311
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 314216154252/(1x138)
LCM = 314216154252/138
LCM = 2276928654
Thus, we can understand that the LCM of 689,966,759,622 is 2276928654.
