Given numbers are 511,739,420,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 511,739,420,255 is 385181580.
Find LCM of 511,739,420,255 with Prime Factorization
| 3 | 511, 739, 420, 255 |
| 5 | 511, 739, 140, 85 |
| 7 | 511, 739, 28, 17 |
| 73, 739, 4, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 73 x 739 x 4 x 17 = 385181580
Therefore, the lowest common multiple of 511,739,420,255 is 385181580.
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.
511 x 739 x 420 x 255 = 40444065900
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.
511 : 1, 7, 73, 511
739 : 1, 739
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,739,420,255, is 1.
Now, the common factors can be found like this.
511:7x 73
739:739
420:2x 2x 3x 5x 7
255:3x 5x 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 5x 7 = 105
Therefore, the value for common factors is 105.
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 = 40444065900/(1x105)
LCM = 40444065900/105
LCM = 385181580
Thus, we can understand that the LCM of 511,739,420,255 is 385181580.
