Given numbers are 138,218,367,705,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,218,367,705,648 is 140108107320.
Find LCM of 138,218,367,705,648 with Prime Factorization
| 2 | 138, 218, 367, 705, 648 |
| 3 | 69, 109, 367, 705, 324 |
| 23, 109, 367, 235, 108 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 109 x 367 x 235 x 108 = 140108107320
Therefore, the lowest common multiple of 138,218,367,705,648 is 140108107320.
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 218 x 367 x 705 x 648 = 5043891863520
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
218 : 1, 2, 109, 218
367 : 1, 367
705 : 1, 3, 5, 15, 47, 141, 235, 705
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,218,367,705,648, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
218:2x 109
367:367
705:3x 5x 47
648:2x 2x 2x 3x 3x 3x 3
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 5043891863520/(1x36)
LCM = 5043891863520/36
LCM = 140108107320
Thus, we can understand that the LCM of 138,218,367,705,648 is 140108107320.
