Given numbers are 124,628,109,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 124,628,109,109 is 2122012.
Find LCM of 124,628,109,109 with Prime Factorization
| 2 | 124, 628, 109, 109 |
| 2 | 62, 314, 109, 109 |
| 109 | 31, 157, 109, 109 |
| 31, 157, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 109 x 31 x 157 x 1 x 1 = 2122012
Therefore, the lowest common multiple of 124,628,109,109 is 2122012.
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.
124 x 628 x 109 x 109 = 925197232
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.
124 : 1, 2, 4, 31, 62, 124
628 : 1, 2, 4, 157, 314, 628
109 : 1, 109
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,628,109,109, is 1.
Now, the common factors can be found like this.
124:2x 2x 31
628:2x 2x 157
109:109
109:109
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 109 = 436
Therefore, the value for common factors is 436.
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 = 925197232/(1x436)
LCM = 925197232/436
LCM = 2122012
Thus, we can understand that the LCM of 124,628,109,109 is 2122012.
