Given numbers are 505,217,128,740,531
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,217,128,740,531 is 275586111360.
Find LCM of 505,217,128,740,531 with Prime Factorization
| 2 | 505, 217, 128, 740, 531 |
| 2 | 505, 217, 64, 370, 531 |
| 5 | 505, 217, 32, 185, 531 |
| 101, 217, 32, 37, 531 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 101 x 217 x 32 x 37 x 531 = 275586111360
Therefore, the lowest common multiple of 505,217,128,740,531 is 275586111360.
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 217 x 128 x 740 x 531 = 5511722227200
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
217 : 1, 7, 31, 217
128 : 1, 2, 4, 8, 16, 32, 64, 128
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,217,128,740,531, is 1.
Now, the common factors can be found like this.
505:5x 101
217:7x 31
128:2x 2x 2x 2x 2x 2x 2
740:2x 2x 5x 37
531:3x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 5511722227200/(1x20)
LCM = 5511722227200/20
LCM = 275586111360
Thus, we can understand that the LCM of 505,217,128,740,531 is 275586111360.
