Given numbers are 427,800,838,525
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,800,838,525 is 429391200.
Find LCM of 427,800,838,525 with Prime Factorization
| 2 | 427, 800, 838, 525 |
| 5 | 427, 400, 419, 525 |
| 5 | 427, 80, 419, 105 |
| 7 | 427, 16, 419, 21 |
| 61, 16, 419, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 7 x 61 x 16 x 419 x 3 = 429391200
Therefore, the lowest common multiple of 427,800,838,525 is 429391200.
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.
427 x 800 x 838 x 525 = 150286920000
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.
427 : 1, 7, 61, 427
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
838 : 1, 2, 419, 838
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,800,838,525, is 1.
Now, the common factors can be found like this.
427:7x 61
800:2x 2x 2x 2x 2x 5x 5
838:2x 419
525:3x 5x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 150286920000/(1x350)
LCM = 150286920000/350
LCM = 429391200
Thus, we can understand that the LCM of 427,800,838,525 is 429391200.
