Given numbers are 718,405,961,690,500
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 718,405,961,690,500 is 321366568500.
Find LCM of 718,405,961,690,500 with Prime Factorization
| 2 | 718, 405, 961, 690, 500 |
| 3 | 359, 405, 961, 345, 250 |
| 5 | 359, 135, 961, 115, 250 |
| 359, 27, 961, 23, 50 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 359 x 27 x 961 x 23 x 50 = 321366568500
Therefore, the lowest common multiple of 718,405,961,690,500 is 321366568500.
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.
718 x 405 x 961 x 690 x 500 = 96409970550000
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.
718 : 1, 2, 359, 718
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
961 : 1, 31, 961
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,405,961,690,500, is 1.
Now, the common factors can be found like this.
718:2x 359
405:3x 3x 3x 3x 5
961:31x 31
690:2x 3x 5x 23
500:2x 2x 5x 5x 5
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 96409970550000/(1x300)
LCM = 96409970550000/300
LCM = 321366568500
Thus, we can understand that the LCM of 718,405,961,690,500 is 321366568500.
