Given numbers are 102,821,504,744
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,821,504,744 is 218064168.
Find LCM of 102,821,504,744 with Prime Factorization
| 2 | 102, 821, 504, 744 |
| 2 | 51, 821, 252, 372 |
| 2 | 51, 821, 126, 186 |
| 3 | 51, 821, 63, 93 |
| 17, 821, 21, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 821 x 21 x 31 = 218064168
Therefore, the lowest common multiple of 102,821,504,744 is 218064168.
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.
102 x 821 x 504 x 744 = 31401240192
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
821 : 1, 821
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,821,504,744, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
821:821
504:2x 2x 2x 3x 3x 7
744:2x 2x 2x 3x 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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 31401240192/(1x144)
LCM = 31401240192/144
LCM = 218064168
Thus, we can understand that the LCM of 102,821,504,744 is 218064168.
