Given numbers are 3670,7720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3670,7720 is 2833240.
Find LCM of 3670,7720 with Prime Factorization
| 2 | 3670, 7720 |
| 5 | 1835, 3860 |
| 367, 772 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 367 x 772 = 2833240
Therefore, the lowest common multiple of 3670,7720 is 2833240.
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.
3670 x 7720 = 28332400
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.
3670 : 1, 2, 5, 10, 367, 734, 1835, 3670
7720 : 1, 2, 4, 5, 8, 10, 20, 40, 193, 386, 772, 965, 1544, 1930, 3860, 7720
10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3670,7720, is 10.
Now, the common factors can be found like this.
3670:2x 5x 367
7720:2x 2x 2x 5x 193
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 = 28332400/(10x1)
LCM = 28332400/10
LCM = 2833240
Thus, we can understand that the LCM of 3670,7720 is 2833240.
