Given numbers are 1560,1299
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1560,1299 is 675480.
Find LCM of 1560,1299 with Prime Factorization
| 3 | 1560, 1299 |
| 520, 433 |
Multiply the prime numbers at the bottom and the left side.
3 x 520 x 433 = 675480
Therefore, the lowest common multiple of 1560,1299 is 675480.
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.
1560 x 1299 = 2026440
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.
1560 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 13, 15, 20, 24, 26, 30, 39, 40, 52, 60, 65, 78, 104, 120, 130, 156, 195, 260, 312, 390, 520, 780, 1560
1299 : 1, 3, 433, 1299
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1560,1299, is 3.
Now, the common factors can be found like this.
1560:2x 2x 2x 3x 5x 13
1299:3x 433
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 = 2026440/(3x1)
LCM = 2026440/3
LCM = 675480
Thus, we can understand that the LCM of 1560,1299 is 675480.
