Given numbers are 203,431,144,420,452
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 203,431,144,420,452 is 7118430480.
Find LCM of 203,431,144,420,452 with Prime Factorization
| 2 | 203, 431, 144, 420, 452 |
| 2 | 203, 431, 72, 210, 226 |
| 3 | 203, 431, 36, 105, 113 |
| 7 | 203, 431, 12, 35, 113 |
| 29, 431, 12, 5, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 29 x 431 x 12 x 5 x 113 = 7118430480
Therefore, the lowest common multiple of 203,431,144,420,452 is 7118430480.
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.
203 x 431 x 144 x 420 x 452 = 2391792641280
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.
203 : 1, 7, 29, 203
431 : 1, 431
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
452 : 1, 2, 4, 113, 226, 452
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,431,144,420,452, is 1.
Now, the common factors can be found like this.
203:7x 29
431:431
144:2x 2x 2x 2x 3x 3
420:2x 2x 3x 5x 7
452:2x 2x 113
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 2x 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 2391792641280/(1x336)
LCM = 2391792641280/336
LCM = 7118430480
Thus, we can understand that the LCM of 203,431,144,420,452 is 7118430480.
