Given numbers are 661,579,243,495
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,579,243,495 is 1705013145.
Find LCM of 661,579,243,495 with Prime Factorization
| 3 | 661, 579, 243, 495 |
| 3 | 661, 193, 81, 165 |
| 661, 193, 27, 55 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 661 x 193 x 27 x 55 = 1705013145
Therefore, the lowest common multiple of 661,579,243,495 is 1705013145.
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.
661 x 579 x 243 x 495 = 46035354915
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.
661 : 1, 661
579 : 1, 3, 193, 579
243 : 1, 3, 9, 27, 81, 243
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,579,243,495, is 1.
Now, the common factors can be found like this.
661:661
579:3x 193
243:3x 3x 3x 3x 3
495:3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 46035354915/(1x27)
LCM = 46035354915/27
LCM = 1705013145
Thus, we can understand that the LCM of 661,579,243,495 is 1705013145.
