Given numbers are 603,122,168,322,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 603,122,168,322,391 is 805400568.
Find LCM of 603,122,168,322,391 with Prime Factorization
| 2 | 603, 122, 168, 322, 391 |
| 3 | 603, 61, 84, 161, 391 |
| 7 | 201, 61, 28, 161, 391 |
| 23 | 201, 61, 4, 23, 391 |
| 201, 61, 4, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 201 x 61 x 4 x 1 x 17 = 805400568
Therefore, the lowest common multiple of 603,122,168,322,391 is 805400568.
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.
603 x 122 x 168 x 322 x 391 = 1556033897376
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.
603 : 1, 3, 9, 67, 201, 603
122 : 1, 2, 61, 122
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
322 : 1, 2, 7, 14, 23, 46, 161, 322
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 603,122,168,322,391, is 1.
Now, the common factors can be found like this.
603:3x 3x 67
122:2x 61
168:2x 2x 2x 3x 7
322:2x 7x 23
391:17x 23
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 3x 7x 23 = 1932
Therefore, the value for common factors is 1932.
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 = 1556033897376/(1x1932)
LCM = 1556033897376/1932
LCM = 805400568
Thus, we can understand that the LCM of 603,122,168,322,391 is 805400568.
