Given numbers are 69,46,86,68,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 69,46,86,68,765 is 3026340.
Find LCM of 69,46,86,68,765 with Prime Factorization
| 2 | 69, 46, 86, 68, 765 |
| 3 | 69, 23, 43, 34, 765 |
| 17 | 23, 23, 43, 34, 255 |
| 23 | 23, 23, 43, 2, 15 |
| 1, 1, 43, 2, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 23 x 1 x 1 x 43 x 2 x 15 = 3026340
Therefore, the lowest common multiple of 69,46,86,68,765 is 3026340.
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.
69 x 46 x 86 x 68 x 765 = 14199587280
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.
69 : 1, 3, 23, 69
46 : 1, 2, 23, 46
86 : 1, 2, 43, 86
68 : 1, 2, 4, 17, 34, 68
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 69,46,86,68,765, is 1.
Now, the common factors can be found like this.
69:3x 23
46:2x 23
86:2x 43
68:2x 2x 17
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 17x 23 = 4692
Therefore, the value for common factors is 4692.
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 = 14199587280/(1x4692)
LCM = 14199587280/4692
LCM = 3026340
Thus, we can understand that the LCM of 69,46,86,68,765 is 3026340.
