Given numbers are 14,43,84,72,124
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 14,43,84,72,124 is 671832.
Find LCM of 14,43,84,72,124 with Prime Factorization
| 2 | 14, 43, 84, 72, 124 |
| 2 | 7, 43, 42, 36, 62 |
| 3 | 7, 43, 21, 18, 31 |
| 7 | 7, 43, 7, 6, 31 |
| 1, 43, 1, 6, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 1 x 43 x 1 x 6 x 31 = 671832
Therefore, the lowest common multiple of 14,43,84,72,124 is 671832.
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.
14 x 43 x 84 x 72 x 124 = 451471104
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.
14 : 1, 2, 7, 14
43 : 1, 43
84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 14,43,84,72,124, is 1.
Now, the common factors can be found like this.
14:2x 7
43:43
84:2x 2x 3x 7
72:2x 2x 2x 3x 3
124:2x 2x 31
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 2x 2x 3x 7 = 672
Therefore, the value for common factors is 672.
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 = 451471104/(1x672)
LCM = 451471104/672
LCM = 671832
Thus, we can understand that the LCM of 14,43,84,72,124 is 671832.
