Given numbers are 676,195,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,195,406 is 2058420.
Find LCM of 676,195,406 with Prime Factorization
| 2 | 676, 195, 406 |
| 13 | 338, 195, 203 |
| 26, 15, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 26 x 15 x 203 = 2058420
Therefore, the lowest common multiple of 676,195,406 is 2058420.
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.
676 x 195 x 406 = 53518920
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
195 : 1, 3, 5, 13, 15, 39, 65, 195
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,195,406, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
195:3x 5x 13
406:2x 7x 29
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 = 53518920/(1x26)
LCM = 53518920/26
LCM = 2058420
Thus, we can understand that the LCM of 676,195,406 is 2058420.
