Given numbers are 253,433,483,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,433,483,455 is 149534385.
Find LCM of 253,433,483,455 with Prime Factorization
| 7 | 253, 433, 483, 455 |
| 23 | 253, 433, 69, 65 |
| 11, 433, 3, 65 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 11 x 433 x 3 x 65 = 149534385
Therefore, the lowest common multiple of 253,433,483,455 is 149534385.
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.
253 x 433 x 483 x 455 = 24075035985
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.
253 : 1, 11, 23, 253
433 : 1, 433
483 : 1, 3, 7, 21, 23, 69, 161, 483
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,433,483,455, is 1.
Now, the common factors can be found like this.
253:11x 23
433:433
483:3x 7x 23
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 24075035985/(1x161)
LCM = 24075035985/161
LCM = 149534385
Thus, we can understand that the LCM of 253,433,483,455 is 149534385.
