Given numbers are 515,523,196,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,523,196,100 is 263958100.
Find LCM of 515,523,196,100 with Prime Factorization
| 2 | 515, 523, 196, 100 |
| 2 | 515, 523, 98, 50 |
| 5 | 515, 523, 49, 25 |
| 103, 523, 49, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 103 x 523 x 49 x 5 = 263958100
Therefore, the lowest common multiple of 515,523,196,100 is 263958100.
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.
515 x 523 x 196 x 100 = 5279162000
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.
515 : 1, 5, 103, 515
523 : 1, 523
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,523,196,100, is 1.
Now, the common factors can be found like this.
515:5x 103
523:523
196:2x 2x 7x 7
100:2x 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 5 = 20
Therefore, the value for common factors is 20.
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 = 5279162000/(1x20)
LCM = 5279162000/20
LCM = 263958100
Thus, we can understand that the LCM of 515,523,196,100 is 263958100.
