Given numbers are 138,853,243,896,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,853,243,896,399 is 81160507008.
Find LCM of 138,853,243,896,399 with Prime Factorization
| 2 | 138, 853, 243, 896, 399 |
| 3 | 69, 853, 243, 448, 399 |
| 7 | 23, 853, 81, 448, 133 |
| 23, 853, 81, 64, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 853 x 81 x 64 x 19 = 81160507008
Therefore, the lowest common multiple of 138,853,243,896,399 is 81160507008.
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 853 x 243 x 896 x 399 = 10226223883008
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
853 : 1, 853
243 : 1, 3, 9, 27, 81, 243
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,853,243,896,399, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
853:853
243:3x 3x 3x 3x 3
896:2x 2x 2x 2x 2x 2x 2x 7
399:3x 7x 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 7 = 126
Therefore, the value for common factors is 126.
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 = 10226223883008/(1x126)
LCM = 10226223883008/126
LCM = 81160507008
Thus, we can understand that the LCM of 138,853,243,896,399 is 81160507008.
