Given numbers are 122,120,723,176
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 122,120,723,176 is 38810640.
Find LCM of 122,120,723,176 with Prime Factorization
| 2 | 122, 120, 723, 176 |
| 2 | 61, 60, 723, 88 |
| 2 | 61, 30, 723, 44 |
| 3 | 61, 15, 723, 22 |
| 61, 5, 241, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 61 x 5 x 241 x 22 = 38810640
Therefore, the lowest common multiple of 122,120,723,176 is 38810640.
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.
122 x 120 x 723 x 176 = 1862910720
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.
122 : 1, 2, 61, 122
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
723 : 1, 3, 241, 723
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,120,723,176, is 1.
Now, the common factors can be found like this.
122:2x 61
120:2x 2x 2x 3x 5
723:3x 241
176:2x 2x 2x 2x 11
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 3 = 48
Therefore, the value for common factors is 48.
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 = 1862910720/(1x48)
LCM = 1862910720/48
LCM = 38810640
Thus, we can understand that the LCM of 122,120,723,176 is 38810640.
