Given numbers are 391,603,134,322
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,603,134,322 is 3300822.
Find LCM of 391,603,134,322 with Prime Factorization
| 2 | 391, 603, 134, 322 |
| 23 | 391, 603, 67, 161 |
| 67 | 17, 603, 67, 7 |
| 17, 9, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 67 x 17 x 9 x 1 x 7 = 3300822
Therefore, the lowest common multiple of 391,603,134,322 is 3300822.
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.
391 x 603 x 134 x 322 = 10173133404
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.
391 : 1, 17, 23, 391
603 : 1, 3, 9, 67, 201, 603
134 : 1, 2, 67, 134
322 : 1, 2, 7, 14, 23, 46, 161, 322
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,603,134,322, is 1.
Now, the common factors can be found like this.
391:17x 23
603:3x 3x 67
134:2x 67
322:2x 7x 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 23x 67 = 3082
Therefore, the value for common factors is 3082.
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 = 10173133404/(1x3082)
LCM = 10173133404/3082
LCM = 3300822
Thus, we can understand that the LCM of 391,603,134,322 is 3300822.
