Given numbers are 483,989,761,903
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 483,989,761,903 is 15805209.
Find LCM of 483,989,761,903 with Prime Factorization
| 3 | 483, 989, 761, 903 |
| 7 | 161, 989, 761, 301 |
| 23 | 23, 989, 761, 43 |
| 43 | 1, 43, 761, 43 |
| 1, 1, 761, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 23 x 43 x 1 x 1 x 761 x 1 = 15805209
Therefore, the lowest common multiple of 483,989,761,903 is 15805209.
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.
483 x 989 x 761 x 903 = 328258385721
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.
483 : 1, 3, 7, 21, 23, 69, 161, 483
989 : 1, 23, 43, 989
761 : 1, 761
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 483,989,761,903, is 1.
Now, the common factors can be found like this.
483:3x 7x 23
989:23x 43
761:761
903:3x 7x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 23x 43 = 20769
Therefore, the value for common factors is 20769.
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 = 328258385721/(1x20769)
LCM = 328258385721/20769
LCM = 15805209
Thus, we can understand that the LCM of 483,989,761,903 is 15805209.
