Given numbers are 243,556,936,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 243,556,936,756 is 24589656.
Find LCM of 243,556,936,756 with Prime Factorization
| 2 | 243, 556, 936, 756 |
| 2 | 243, 278, 468, 378 |
| 3 | 243, 139, 234, 189 |
| 3 | 81, 139, 78, 63 |
| 3 | 27, 139, 26, 21 |
| 9, 139, 26, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 9 x 139 x 26 x 7 = 24589656
Therefore, the lowest common multiple of 243,556,936,756 is 24589656.
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.
243 x 556 x 936 x 756 = 95604582528
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.
243 : 1, 3, 9, 27, 81, 243
556 : 1, 2, 4, 139, 278, 556
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,556,936,756, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
556:2x 2x 139
936:2x 2x 2x 3x 3x 13
756:2x 2x 3x 3x 3x 7
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 3x 3x 3x 3 = 3888
Therefore, the value for common factors is 3888.
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 = 95604582528/(1x3888)
LCM = 95604582528/3888
LCM = 24589656
Thus, we can understand that the LCM of 243,556,936,756 is 24589656.
