Given numbers are 505,273,649,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,273,649,663 is 1521064545.
Find LCM of 505,273,649,663 with Prime Factorization
| 3 | 505, 273, 649, 663 |
| 13 | 505, 91, 649, 221 |
| 505, 7, 649, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 505 x 7 x 649 x 17 = 1521064545
Therefore, the lowest common multiple of 505,273,649,663 is 1521064545.
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 273 x 649 x 663 = 59321517255
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
273 : 1, 3, 7, 13, 21, 39, 91, 273
649 : 1, 11, 59, 649
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,273,649,663, is 1.
Now, the common factors can be found like this.
505:5x 101
273:3x 7x 13
649:11x 59
663:3x 13x 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 13 = 39
Therefore, the value for common factors is 39.
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 = 59321517255/(1x39)
LCM = 59321517255/39
LCM = 1521064545
Thus, we can understand that the LCM of 505,273,649,663 is 1521064545.
