Given numbers are 505,493,901,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,493,901,909 is 118756305.
Find LCM of 505,493,901,909 with Prime Factorization
| 17 | 505, 493, 901, 909 |
| 101 | 505, 29, 53, 909 |
| 5, 29, 53, 9 |
Multiply the prime numbers at the bottom and the left side.
17 x 101 x 5 x 29 x 53 x 9 = 118756305
Therefore, the lowest common multiple of 505,493,901,909 is 118756305.
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.
505 x 493 x 901 x 909 = 203904575685
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.
505 : 1, 5, 101, 505
493 : 1, 17, 29, 493
901 : 1, 17, 53, 901
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,493,901,909, is 1.
Now, the common factors can be found like this.
505:5x 101
493:17x 29
901:17x 53
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 101 = 1717
Therefore, the value for common factors is 1717.
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 = 203904575685/(1x1717)
LCM = 203904575685/1717
LCM = 118756305
Thus, we can understand that the LCM of 505,493,901,909 is 118756305.
