The LCM of 7,539,765,459 is 1237005.
Find LCM of 7,539,765,459 with Prime Factorization
| 3 | 7, 539, 765, 459 |
| 3 | 7, 539, 255, 153 |
| 7 | 7, 539, 85, 51 |
| 17 | 1, 77, 85, 51 |
| 1, 77, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 17 x 1 x 77 x 5 x 3 = 1237005
Therefore, the lowest common multiple of 7,539,765,459 is 1237005.
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.
7 x 539 x 765 x 459 = 1324832355
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.
7 : 1, 7
539 : 1, 7, 11, 49, 77, 539
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
459 : 1, 3, 9, 17, 27, 51, 153, 459
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,539,765,459, is 1.
Now, the common factors can be found like this.
7:7
539:7x 7x 11
765:3x 3x 5x 17
459:3x 3x 3x 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 7x 17 = 1071
Therefore, the value for common factors is 1071.
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 = 1324832355/(1x1071)
LCM = 1324832355/1071
LCM = 1237005
Thus, we can understand that the LCM of 7,539,765,459 is 1237005.
