Given numbers are 689,806,947,341
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,806,947,341 is 444993406.
Find LCM of 689,806,947,341 with Prime Factorization
| 13 | 689, 806, 947, 341 |
| 31 | 53, 62, 947, 341 |
| 53, 2, 947, 11 |
Multiply the prime numbers at the bottom and the left side.
13 x 31 x 53 x 2 x 947 x 11 = 444993406
Therefore, the lowest common multiple of 689,806,947,341 is 444993406.
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 806 x 947 x 341 = 179332342618
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
806 : 1, 2, 13, 26, 31, 62, 403, 806
947 : 1, 947
341 : 1, 11, 31, 341
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,806,947,341, is 1.
Now, the common factors can be found like this.
689:13x 53
806:2x 13x 31
947:947
341:11x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 31 = 403
Therefore, the value for common factors is 403.
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 = 179332342618/(1x403)
LCM = 179332342618/403
LCM = 444993406
Thus, we can understand that the LCM of 689,806,947,341 is 444993406.
