Given numbers are 1615,4290
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1615,4290 is 1385670.
Find LCM of 1615,4290 with Prime Factorization
| 5 | 1615, 4290 |
| 323, 858 |
Multiply the prime numbers at the bottom and the left side.
5 x 323 x 858 = 1385670
Therefore, the lowest common multiple of 1615,4290 is 1385670.
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.
1615 x 4290 = 6928350
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.
1615 : 1, 5, 17, 19, 85, 95, 323, 1615
4290 : 1, 2, 3, 5, 6, 10, 11, 13, 15, 22, 26, 30, 33, 39, 55, 65, 66, 78, 110, 130, 143, 165, 195, 286, 330, 390, 429, 715, 858, 1430, 2145, 4290
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1615,4290, is 5.
Now, the common factors can be found like this.
1615:5x 17x 19
4290:2x 3x 5x 11x 13
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 = 6928350/(5x1)
LCM = 6928350/5
LCM = 1385670
Thus, we can understand that the LCM of 1615,4290 is 1385670.
