Given numbers are 5780,5457
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 5780,5457 is 1855380.
Find LCM of 5780,5457 with Prime Factorization
| 17 | 5780, 5457 |
| 340, 321 |
Multiply the prime numbers at the bottom and the left side.
17 x 340 x 321 = 1855380
Therefore, the lowest common multiple of 5780,5457 is 1855380.
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.
5780 x 5457 = 31541460
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.
5780 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 289, 340, 578, 1156, 1445, 2890, 5780
5457 : 1, 3, 17, 51, 107, 321, 1819, 5457
17 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 5780,5457, is 17.
Now, the common factors can be found like this.
5780:2x 2x 5x 17x 17
5457:3x 17x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 31541460/(17x1)
LCM = 31541460/17
LCM = 1855380
Thus, we can understand that the LCM of 5780,5457 is 1855380.
