Given numbers are 495,831,712,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 495,831,712,765 is 1659639960.
Find LCM of 495,831,712,765 with Prime Factorization
| 3 | 495, 831, 712, 765 |
| 3 | 165, 277, 712, 255 |
| 5 | 55, 277, 712, 85 |
| 11, 277, 712, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 277 x 712 x 17 = 1659639960
Therefore, the lowest common multiple of 495,831,712,765 is 1659639960.
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.
495 x 831 x 712 x 765 = 224051394600
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
831 : 1, 3, 277, 831
712 : 1, 2, 4, 8, 89, 178, 356, 712
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,831,712,765, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
831:3x 277
712:2x 2x 2x 89
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 224051394600/(1x135)
LCM = 224051394600/135
LCM = 1659639960
Thus, we can understand that the LCM of 495,831,712,765 is 1659639960.
