Given numbers are 138,575,141,121,684
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,575,141,121,684 is 2236697100.
Find LCM of 138,575,141,121,684 with Prime Factorization
| 2 | 138, 575, 141, 121, 684 |
| 3 | 69, 575, 141, 121, 342 |
| 23 | 23, 575, 47, 121, 114 |
| 1, 25, 47, 121, 114 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 1 x 25 x 47 x 121 x 114 = 2236697100
Therefore, the lowest common multiple of 138,575,141,121,684 is 2236697100.
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.
138 x 575 x 141 x 121 x 684 = 925992599400
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
575 : 1, 5, 23, 25, 115, 575
141 : 1, 3, 47, 141
121 : 1, 11, 121
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,575,141,121,684, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
575:5x 5x 23
141:3x 47
121:11x 11
684:2x 2x 3x 3x 19
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 3x 23 = 414
Therefore, the value for common factors is 414.
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 = 925992599400/(1x414)
LCM = 925992599400/414
LCM = 2236697100
Thus, we can understand that the LCM of 138,575,141,121,684 is 2236697100.
