Given numbers are 102,685,252,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,685,252,822 is 2934540.
Find LCM of 102,685,252,822 with Prime Factorization
| 2 | 102, 685, 252, 822 |
| 3 | 51, 685, 126, 411 |
| 137 | 17, 685, 42, 137 |
| 17, 5, 42, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 17 x 5 x 42 x 1 = 2934540
Therefore, the lowest common multiple of 102,685,252,822 is 2934540.
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 685 x 252 x 822 = 14473151280
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
685 : 1, 5, 137, 685
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,685,252,822, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
685:5x 137
252:2x 2x 3x 3x 7
822:2x 3x 137
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 3x 137 = 4932
Therefore, the value for common factors is 4932.
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 = 14473151280/(1x4932)
LCM = 14473151280/4932
LCM = 2934540
Thus, we can understand that the LCM of 102,685,252,822 is 2934540.
