Given numbers are 585,437,320,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 585,437,320,390 is 16361280.
Find LCM of 585,437,320,390 with Prime Factorization
| 2 | 585, 437, 320, 390 |
| 3 | 585, 437, 160, 195 |
| 5 | 65, 437, 160, 195 |
| 13 | 13, 437, 32, 39 |
| 1, 437, 32, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 1 x 437 x 32 x 3 = 16361280
Therefore, the lowest common multiple of 585,437,320,390 is 16361280.
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.
585 x 437 x 320 x 390 = 31904496000
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.
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
437 : 1, 19, 23, 437
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,437,320,390, is 1.
Now, the common factors can be found like this.
585:3x 3x 5x 13
437:19x 23
320:2x 2x 2x 2x 2x 2x 5
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 13 = 1950
Therefore, the value for common factors is 1950.
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 = 31904496000/(1x1950)
LCM = 31904496000/1950
LCM = 16361280
Thus, we can understand that the LCM of 585,437,320,390 is 16361280.
