Given numbers are 506,361,255,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 506,361,255,665 is 326058810.
Find LCM of 506,361,255,665 with Prime Factorization
| 5 | 506, 361, 255, 665 |
| 19 | 506, 361, 51, 133 |
| 506, 19, 51, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 19 x 506 x 19 x 51 x 7 = 326058810
Therefore, the lowest common multiple of 506,361,255,665 is 326058810.
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.
506 x 361 x 255 x 665 = 30975586950
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.
506 : 1, 2, 11, 22, 23, 46, 253, 506
361 : 1, 19, 361
255 : 1, 3, 5, 15, 17, 51, 85, 255
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 506,361,255,665, is 1.
Now, the common factors can be found like this.
506:2x 11x 23
361:19x 19
255:3x 5x 17
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 19 = 95
Therefore, the value for common factors is 95.
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 = 30975586950/(1x95)
LCM = 30975586950/95
LCM = 326058810
Thus, we can understand that the LCM of 506,361,255,665 is 326058810.
