Given numbers are 676,719,687,916
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,719,687,916 is 333912228.
Find LCM of 676,719,687,916 with Prime Factorization
| 2 | 676, 719, 687, 916 |
| 2 | 338, 719, 687, 458 |
| 229 | 169, 719, 687, 229 |
| 169, 719, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 229 x 169 x 719 x 3 x 1 = 333912228
Therefore, the lowest common multiple of 676,719,687,916 is 333912228.
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 719 x 687 x 916 = 305863600848
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
719 : 1, 719
687 : 1, 3, 229, 687
916 : 1, 2, 4, 229, 458, 916
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,719,687,916, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
719:719
687:3x 229
916:2x 2x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 229 = 916
Therefore, the value for common factors is 916.
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 = 305863600848/(1x916)
LCM = 305863600848/916
LCM = 333912228
Thus, we can understand that the LCM of 676,719,687,916 is 333912228.
