Given numbers are 647,403,277,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,403,277,806 is 144450514.
Find LCM of 647,403,277,806 with Prime Factorization
| 13 | 647, 403, 277, 806 |
| 31 | 647, 31, 277, 62 |
| 647, 1, 277, 2 |
Multiply the prime numbers at the bottom and the left side.
13 x 31 x 647 x 1 x 277 x 2 = 144450514
Therefore, the lowest common multiple of 647,403,277,806 is 144450514.
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.
647 x 403 x 277 x 806 = 58213557142
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.
647 : 1, 647
403 : 1, 13, 31, 403
277 : 1, 277
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,403,277,806, is 1.
Now, the common factors can be found like this.
647:647
403:13x 31
277:277
806:2x 13x 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 = 58213557142/(1x403)
LCM = 58213557142/403
LCM = 144450514
Thus, we can understand that the LCM of 647,403,277,806 is 144450514.
