Given numbers are 388,174,307,124
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,174,307,124 is 321255852.
Find LCM of 388,174,307,124 with Prime Factorization
| 2 | 388, 174, 307, 124 |
| 2 | 194, 87, 307, 62 |
| 97, 87, 307, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 97 x 87 x 307 x 31 = 321255852
Therefore, the lowest common multiple of 388,174,307,124 is 321255852.
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.
388 x 174 x 307 x 124 = 2570046816
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.
388 : 1, 2, 4, 97, 194, 388
174 : 1, 2, 3, 6, 29, 58, 87, 174
307 : 1, 307
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 388,174,307,124, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
174:2x 3x 29
307:307
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 2 = 8
Therefore, the value for common factors is 8.
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 = 2570046816/(1x8)
LCM = 2570046816/8
LCM = 321255852
Thus, we can understand that the LCM of 388,174,307,124 is 321255852.
