Given numbers are 67,18,78,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 67,18,78,871 is 15678.
Find LCM of 67,18,78,871 with Prime Factorization
2 | 67, 18, 78, 871 |
3 | 67, 9, 39, 871 |
13 | 67, 3, 13, 871 |
67 | 67, 3, 1, 67 |
1, 3, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 67 x 1 x 3 x 1 x 1 = 15678
Therefore, the lowest common multiple of 67,18,78,871 is 15678.
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.
67 x 18 x 78 x 871 = 81933228
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.
67 : 1, 67
18 : 1, 2, 3, 6, 9, 18
78 : 1, 2, 3, 6, 13, 26, 39, 78
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 67,18,78,871, is 1.
Now, the common factors can be found like this.
67:67
18:2x 3x 3
78:2x 3x 13
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 67 = 5226
Therefore, the value for common factors is 5226.
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 = 81933228/(1x5226)
LCM = 81933228/5226
LCM = 15678
Thus, we can understand that the LCM of 67,18,78,871 is 15678.
