Given numbers are 383,242,452,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 383,242,452,440 is 209470360.
Find LCM of 383,242,452,440 with Prime Factorization
| 2 | 383, 242, 452, 440 |
| 2 | 383, 121, 226, 220 |
| 11 | 383, 121, 113, 110 |
| 383, 11, 113, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 383 x 11 x 113 x 10 = 209470360
Therefore, the lowest common multiple of 383,242,452,440 is 209470360.
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.
383 x 242 x 452 x 440 = 18433391680
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.
383 : 1, 383
242 : 1, 2, 11, 22, 121, 242
452 : 1, 2, 4, 113, 226, 452
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 383,242,452,440, is 1.
Now, the common factors can be found like this.
383:383
242:2x 11x 11
452:2x 2x 113
440:2x 2x 2x 5x 11
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 11 = 88
Therefore, the value for common factors is 88.
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 = 18433391680/(1x88)
LCM = 18433391680/88
LCM = 209470360
Thus, we can understand that the LCM of 383,242,452,440 is 209470360.
