Given numbers are 522,103,420,449
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 522,103,420,449 is 1689865380.
Find LCM of 522,103,420,449 with Prime Factorization
| 2 | 522, 103, 420, 449 |
| 3 | 261, 103, 210, 449 |
| 87, 103, 70, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 87 x 103 x 70 x 449 = 1689865380
Therefore, the lowest common multiple of 522,103,420,449 is 1689865380.
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.
522 x 103 x 420 x 449 = 10139192280
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.
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
103 : 1, 103
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
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 522,103,420,449, is 1.
Now, the common factors can be found like this.
522:2x 3x 3x 29
103:103
420:2x 2x 3x 5x 7
449:449
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 10139192280/(1x6)
LCM = 10139192280/6
LCM = 1689865380
Thus, we can understand that the LCM of 522,103,420,449 is 1689865380.
