Given numbers are 86,87,66,66,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 86,87,66,66,748 is 2798268.
Find LCM of 86,87,66,66,748 with Prime Factorization
| 2 | 86, 87, 66, 66, 748 |
| 3 | 43, 87, 33, 33, 374 |
| 11 | 43, 29, 11, 11, 374 |
| 43, 29, 1, 1, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 43 x 29 x 1 x 1 x 34 = 2798268
Therefore, the lowest common multiple of 86,87,66,66,748 is 2798268.
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.
86 x 87 x 66 x 66 x 748 = 24378510816
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.
86 : 1, 2, 43, 86
87 : 1, 3, 29, 87
66 : 1, 2, 3, 6, 11, 22, 33, 66
66 : 1, 2, 3, 6, 11, 22, 33, 66
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 86,87,66,66,748, is 1.
Now, the common factors can be found like this.
86:2x 43
87:3x 29
66:2x 3x 11
66:2x 3x 11
748:2x 2x 11x 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 2x 3x 3x 11x 11 = 8712
Therefore, the value for common factors is 8712.
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 = 24378510816/(1x8712)
LCM = 24378510816/8712
LCM = 2798268
Thus, we can understand that the LCM of 86,87,66,66,748 is 2798268.
