Given numbers are 8180,7230
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8180,7230 is 5914140.
Find LCM of 8180,7230 with Prime Factorization
| 2 | 8180, 7230 |
| 5 | 4090, 3615 |
| 818, 723 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 818 x 723 = 5914140
Therefore, the lowest common multiple of 8180,7230 is 5914140.
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.
8180 x 7230 = 59141400
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.
8180 : 1, 2, 4, 5, 10, 20, 409, 818, 1636, 2045, 4090, 8180
7230 : 1, 2, 3, 5, 6, 10, 15, 30, 241, 482, 723, 1205, 1446, 2410, 3615, 7230
10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8180,7230, is 10.
Now, the common factors can be found like this.
8180:2x 2x 5x 409
7230:2x 3x 5x 241
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 = 59141400/(10x1)
LCM = 59141400/10
LCM = 5914140
Thus, we can understand that the LCM of 8180,7230 is 5914140.
