Given numbers are 8135,7140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8135,7140 is 11616780.
Find LCM of 8135,7140 with Prime Factorization
| 5 | 8135, 7140 |
| 1627, 1428 |
Multiply the prime numbers at the bottom and the left side.
5 x 1627 x 1428 = 11616780
Therefore, the lowest common multiple of 8135,7140 is 11616780.
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.
8135 x 7140 = 58083900
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.
8135 : 1, 5, 1627, 8135
7140 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 17, 20, 21, 28, 30, 34, 35, 42, 51, 60, 68, 70, 84, 85, 102, 105, 119, 140, 170, 204, 210, 238, 255, 340, 357, 420, 476, 510, 595, 714, 1020, 1190, 1428, 1785, 2380, 3570, 7140
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8135,7140, is 5.
Now, the common factors can be found like this.
8135:5x 1627
7140:2x 2x 3x 5x 7x 17
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 = 58083900/(5x1)
LCM = 58083900/5
LCM = 11616780
Thus, we can understand that the LCM of 8135,7140 is 11616780.
