Given numbers are 4030,8040
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 4030,8040 is 3240120.
Find LCM of 4030,8040 with Prime Factorization
| 2 | 4030, 8040 |
| 5 | 2015, 4020 |
| 403, 804 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 403 x 804 = 3240120
Therefore, the lowest common multiple of 4030,8040 is 3240120.
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.
4030 x 8040 = 32401200
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.
4030 : 1, 2, 5, 10, 13, 26, 31, 62, 65, 130, 155, 310, 403, 806, 2015, 4030
8040 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 67, 120, 134, 201, 268, 335, 402, 536, 670, 804, 1005, 1340, 1608, 2010, 2680, 4020, 8040
10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4030,8040, is 10.
Now, the common factors can be found like this.
4030:2x 5x 13x 31
8040:2x 2x 2x 3x 5x 67
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 = 32401200/(10x1)
LCM = 32401200/10
LCM = 3240120
Thus, we can understand that the LCM of 4030,8040 is 3240120.
