Given numbers are 260,170,575,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 260,170,575,578 is 8641100.
Find LCM of 260,170,575,578 with Prime Factorization
| 2 | 260, 170, 575, 578 |
| 5 | 130, 85, 575, 289 |
| 17 | 26, 17, 115, 289 |
| 26, 1, 115, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 26 x 1 x 115 x 17 = 8641100
Therefore, the lowest common multiple of 260,170,575,578 is 8641100.
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.
260 x 170 x 575 x 578 = 14689870000
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
170 : 1, 2, 5, 10, 17, 34, 85, 170
575 : 1, 5, 23, 25, 115, 575
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,170,575,578, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
170:2x 5x 17
575:5x 5x 23
578:2x 17x 17
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 17 = 1700
Therefore, the value for common factors is 1700.
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 = 14689870000/(1x1700)
LCM = 14689870000/1700
LCM = 8641100
Thus, we can understand that the LCM of 260,170,575,578 is 8641100.
