Given numbers are 723,690,243,406,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,690,243,406,402 is 183198533490.
Find LCM of 723,690,243,406,402 with Prime Factorization
2 | 723, 690, 243, 406, 402 |
3 | 723, 345, 243, 203, 201 |
241, 115, 81, 203, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 241 x 115 x 81 x 203 x 67 = 183198533490
Therefore, the lowest common multiple of 723,690,243,406,402 is 183198533490.
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.
723 x 690 x 243 x 406 x 402 = 19785441616920
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.
723 : 1, 3, 241, 723
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
243 : 1, 3, 9, 27, 81, 243
406 : 1, 2, 7, 14, 29, 58, 203, 406
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,690,243,406,402, is 1.
Now, the common factors can be found like this.
723:3x 241
690:2x 3x 5x 23
243:3x 3x 3x 3x 3
406:2x 7x 29
402:2x 3x 67
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 3 = 108
Therefore, the value for common factors is 108.
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 = 19785441616920/(1x108)
LCM = 19785441616920/108
LCM = 183198533490
Thus, we can understand that the LCM of 723,690,243,406,402 is 183198533490.
