Given numbers are 545,109,406,890,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,109,406,890,400 is 787721200.
Find LCM of 545,109,406,890,400 with Prime Factorization
| 2 | 545, 109, 406, 890, 400 |
| 5 | 545, 109, 203, 445, 200 |
| 109 | 109, 109, 203, 89, 40 |
| 1, 1, 203, 89, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 109 x 1 x 1 x 203 x 89 x 40 = 787721200
Therefore, the lowest common multiple of 545,109,406,890,400 is 787721200.
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.
545 x 109 x 406 x 890 x 400 = 8586161080000
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.
545 : 1, 5, 109, 545
109 : 1, 109
406 : 1, 2, 7, 14, 29, 58, 203, 406
890 : 1, 2, 5, 10, 89, 178, 445, 890
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,109,406,890,400, is 1.
Now, the common factors can be found like this.
545:5x 109
109:109
406:2x 7x 29
890:2x 5x 89
400:2x 2x 2x 2x 5x 5
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 5x 5x 109 = 10900
Therefore, the value for common factors is 10900.
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 = 8586161080000/(1x10900)
LCM = 8586161080000/10900
LCM = 787721200
Thus, we can understand that the LCM of 545,109,406,890,400 is 787721200.
